How to deal with low power factor (PF) in DG sets? - Part 2


Robust Power Factor correction systems have been designed by expert power electronics developers as per the given limitations and system boundaries (in Part 1). The newly designed systems deploy the principles of the conventional Automatic Power Factor Corrector (APFC) but they differ significantly on aspects like the control logics and subsequently the controller hardware that are cutting-edge and sophisticated. In common language, this corrective mechanism is known as reactive power consumption whereby a mirror image of the tracked power factor is formed to correct it in real time.

To put this into effect you would need the below things:

1.      Thyristors with solid state relays - As the name itself suggests and unlike the conventional magnetic induction relays, these are made up of solid state electronics (semiconductors) that are helpful in eliminating transient currents and reducing the time lag between the consecutive switchovers of capacitors.

2.      Multiple current sensors-A current transformer should be available for every electrical phase of the layout. It will virtually balance the load and correct the power factor on every phase line.

3.      Microprocessor-based controllers - The additional phase-wise data parameters and the calculation of power for correction determination have rendered micro controller based controllers slow and sluggish. That is why hardcoded PLCs or faster microprocessors work better than them.


Advantages of correcting the Power Factor with the above advanced methods:

1.      More alternator efficiency- The copper losses that are associated with an alternator are directly proportional to the square of the current that it delivers. Thus, the correction of power factorwill lead to lesser current per unit power and reduce the associated copper loss.

2.      Reduced overheating and voltage fluctuations - There’ll be reduction in the currents in the total system. Due to this, overheating and voltage fluctuations in the windings and the transmission network due to the shuttling of loads is greatly reduced. This further saves T&D losses.

Low power factor in dg sets – Part 1

The state of power supply has been erratic for a long time and many areas in the country are still struggling for a reliable source of electricity. Especially the industries that need uninterrupted power supply for economic sustainability have shown a tremendous rise in moving to diesel generators as an important source of electricity and not just a temporary arrangement. With the increase in usage and desirability of diesel generators the need to find ways to improve their efficiency and power factor (PF) is also on the rise.

What are the causes of low power factor?

Different load sizes that come with different power factor effects is the primary cause for the overall reduction in the power factor of an electrical layout. But various other reasons contribute to power factor output being low and in a significant way. The reasons are primarily connected to the fundamental limitations of a power generator.
A diesel power generator is a source of power that doesn’t have a network of sources and loads to load it. Thus, it has a limited capacity to fulfill sudden and large demands of reactive power. To build more on this limitation, the below can be associated as reasons why there is lower power factor in dg sets:

1.      Over sized dg sets

Designers of a plant usually tend to oversize a dg set or limit its loading owing to a largely existent myth that 0.8 is the ‘designed’ PF for dg sets. This essentially leads to liberally sized diesel guzzlers that do not deliver the full version of their economic capability. The alternator of a dg set is same as its larger variants connected to utility power turbines with scaled down proportions. Which means that it by design has the capability to deliver the exact amount rated as its KVA (kilovolt-ampere). So, 0.8 is not a design variable but it’s more like a thumb rule inferred from the average power factor in any industrial electrical layout with a general set of inductive - PF values .8 to .85, non-linear – Power Factor values .5 to .65 and linear (unity PF) - 0.80.

2.      Phase loading that’s unbalanced

Most of the industrial electrical layouts have loads that are liberally connected on various power phase lines because physical limitations of the process layouts are simpler to visualize when compared to the electrical balancing on every line. This doesn’t seem to be a problem when it comes to the grid connected situation where the primary connection of a phase maintains the sync in the remaining from the utility side owing to a grid’s macro effect. But in the case of a dg set that’s’ captive, syncing the phases is not even a function built into its power electronics.

3.      The load of compensation

From various reports on the effect of different power factors on dg sets and detecting safe zones it has become evident that close to unity Power Factor is achievable and safer but low Power Factor for greater periods has more negative impact.

This is part one of a two-part series. In the second part, learn how to correct dg sets with low Power Factor.

Parts of a diesel generator and their functions.

We all know that a diesel generator is used as a source of backup when supply of power is not constant. They have assumed great importance and have almost become a necessity for households and companies in areas where there is a shortage of electrical supply. Given the promising nature of a diesel generator, we all have at some point used it or at least have known its merits. But have we ever tried to understand what are the various parts that power the diesel generator and help it function?

Let us look at some of the main components of a diesel generator and their functions:
1.       Engine – The heart of the system
The function of the engine is to create the mechanical energy that the diesel generator converts into electricity. The design of the engine is aimed at generating a maximum supply of electrical current by running on diesel or other alternate fuels.

2.       A comprehensive fuel system
Generators that run on diesel or any other fuel, have a fuel system that stores and pumps it to the engine. The tank stores a good amount of fuel to power the generator for several hours at a stretch. A fuel pipe in the system connects the tank to the engine while a return pipe connects the engine to the fuel tank for the return of fuel. A fuel pump moves fuel from the tank through fuel pipe and to the engine. There is a fuel filter which filters out debris from the fuel, if any before delivering it to the engine. A fuel injector atomizes and injects the fuel directly into the combustion chamber of the engine.

The alternator in a diesel generator converts mechanical energy produced by the engine into electrical current. It comprises of the stator and the rotor (or armature). The stator is stationary and contains a set of coils that conduct electricity. The rotor moves to create a constantly rotating electromagnetic field around the stator.

4.       Voltage Regulator
The alternator may generate electrical voltage but the level of voltage needs to be regulated that is suitable for practical use. Voltage regulator is an electrical regulator that maintains a constant level of voltage.

5.       Impeccable cooling and exhaust systems
The temperature of a diesel generator must be regulated to prevent overheating while being used. Generators can use a fan, coolant or both to control the temperature of the generator at work. The internal combustion engines are usually cooled by passing engine coolant through the engine block. The generator also produces exhaust as the combustion chamber converts fuel. There are exhaust systems that dispel harmful gases emitted.

6.       Lubrication system
A diesel generator comprises of various moving parts. These parts need to be oiled for their smooth functioning. The lubrication system ensures that the parts are well oiled and functioning at their best.

7.       Acoustic Enclosure
Being a mechanical product with many moving parts, a diesel engine makes lot of noise during its operation. In order to control the noise emission, the engine and alternator assembly is housed in a soundproof canopy having sound absorbent material from inside. As per Central Pollution Control Board (CPCB), the maximum noise emission from a generator should not exceed 75 dBA from 1 m distance from the canopy.

QUICK HACKS TO SAVE ENERGY

Even though electricity is a luxury in various regions of India, it is often taken for granted by people who reside in towns and metropolitan cities. So much so that some months your electricity usage, as apparent from your bills, makes you break out into a cold sweat. Also, with summers around, power usage will soar more than ever.

It is high time that we as responsible citizens do our bit to save some energy so that the rest of the country can benefit from it. Shared below are quick hacks to save energy:

AC can be best set at an optimum temperature of 24 degrees 


We all know that AC’s suck up a major chunk of electricity hence to save energy and for optimum results, try setting up your AC at 24 degrees and not lower than that.

Appliances should be switched off when not in use

You must know that any electrical appliance when left unattended and is in standby mode still consumes electricity. In fact, devices on standby suck up a whopping 5% of the total electricity consumption. This is a serious reason to switch off all your appliances when not in use. Mobile phone chargers when left plugged in with switches still on tend to still consume power. So, do remember to turn the switch off.

The right kind of lights can help save a lot of energy

The variety of lights you choose to use can be the most effective way to save on power. The right kind of lights can make all the difference in the amount of electricity you consume. Compact-sized fluorescent bulbs may offer almost the same amount of light and brightness as in the case of incandescent bulbs. But the fact remains that they are 4 times more energy efficient. So, while these bulbs are more expensive than the regular ones, they do use much less energy and last relatively longer. In certain cases, they may last for as long as a year.

Use your iron wisely

Whether you believe it or no, here’s telling you that your iron can contribute to your energy-saving pursuit. In case you’re about to buy an iron, ensure buying one which has an automatic temperature cut-off. Do not wet your clothes before you iron them, this will ensure low power consumption.

Keep your fridge organized always

When you have a crowded fridge, there is less room for the air to efficiently circulate. With that, your fridge starts working harder to keep cool. The harder it works; the more electricity it consumes. On the other hand, the more organised your freezer, the better it works. The thermostat of your fridge should always be in the medium cooling position. Do not put in hot or warm foods straightaway. The liquids must always be covered and food must be wrapped up so that they do not moisten which can cause the compressor to work extra hard.




Pay attention to your washing machine

When you fill up your washing machine to the brim with soiled clothes, and use the right amount of detergent, it works most efficiently. That said, do not overload the machine leading it to cope harder and using up more power. Cold water may be optimally utilized when the clothes are not too dirty. Dry out your clothes naturally, make use of a timer facility if need be. When you make use of cooler and less water you end up saving about 80% to 85% of the energy utilized in washing clothes. 




Give that electrical dryer a miss unless you absolutely cannot

For tropical monsoon climates, there may be no other option than using electric dryers from time to time. Dryers consume electricity enormously. If you must absolutely use one, dry your clothes in consecutive loads.

Opt for an Eco-friendly shower

Your shower could be an energy-friendly one when you switch the geyser off after 10 minutes of it running. In case you cannot do without hot water, decrease the thermostat, setting it to 50 degrees. If you can, do use a solar water heater. This is a much Eco-friendlier alternative to a regular water heater.

Use a microwave to cook whenever you can 

Microwaves consume half as much energy as a regular electric stove. You never need to preheat a microwave unless if you want to bake. Also, if you must check on your food, refrain from doing it ever so often. Every time you open the door of your microwave the temperature drops by 25 degrees and will need to consume a lot more energy to pick up back again. 

A pressure cooker saves electricity too

Whenever you can, make use of a pressure cooker to cook. It will save you time as well as energy. Let any items that you got out from the fridge to settle to room temperature by leaving it outside for at least 10 minutes, and only then cook them.

Create shaded spaces around your house

Potted plants don’t just look pleasing, but they can also serve to be amazing energy-savers. You may line them up outside of your house. This will keep the sun from shining straight onto your AC. An air conditioning unit that operates in a shaded space needs up to 100% less electricity than one exposed to the sun.

Hope these hacks will prove to be helpful to you in saving electricity.

A Close Look at Wet Stacking of Diesel Generators – Effects, Prevention and Solution

Diesel as a source of fuel is conveniently independent and its compression ignition systems have a higher thermal efficiency than that of gas engines that use the spark ignition systems. That said, an important factor to be considered when choosing a diesel generator is its potential for ‘wet stacking’. Diesel generator designers must bring into account the potential for wet stacking when they determine the equipment for the system, maintenance, service programs and load calculations. Further, this post will discuss the adverse effects of wet stacking on your diesel generator and methods you can use to eliminate the condition.

What is wet stacking?

Just like all internal combustion engines, a generator must have exactly the right amount of air-to-fuel ratio to operate at its best efficiency and deliver optimum results. It should be able to utilize its designed operational temperature so that the fuel can burn out completely. Diesel generators rely on the hot compressed air in the cylinder to ignite the fuel. Because the air is cooler than the design temperature, the conditions for combustion are not ideal. Thus, the fuel ignites, but it doesn’t burn completely. The unburned fuel exhausts and results into wetness in the exhaust system. Hence, the phrase, wet stacking.

How do you know if your generator is wet stacking?

Your diesel generator may likely be performing inefficiently if one or all the below conditions exist:-

There’s a continuous release of black exhaust smoke from your diesel generator’s exhaust pipe.
A thick, dark substance is continually dripping from the exhaust pipes.
There’s a formation of deposits of soot or hard carbons.

Effects wet stacking has on your generator

Raised expenses: Wet stacking can shorten the life of the engine of your diesel generator by many years and you may have to replace it much before than you planned to.

Air pollution: The level of smoke emissions produced due to wet stacking is restricted in many urban areas.

Low power: The deposits caused due to wet stacking will reduce the maximum power of your diesel generator even before the engine is damaged.

Higher maintenance: A diesel generator that is experiencing wet stacking will need considerably higher maintenance than one which is adequately loaded.

Prevention and Solution:

The basic solution for wet stacking is a few hours of operation at a load of about 75% of the generator’s nameplate rating (or more) to raise the exhaust temperature high enough so that the unburned fuel in the exhaust system can be vaporized and the soot can be blown out away. At the same time, the exhaust temperature at that load is higher than the auto-ignition temperature for diesel which on rare occasions can ignite fuel and soot within the exhaust system. In case a unit has a history of extended operation at low load, or if there’s no proof that it’s been exercised recently at adequate load, it’s vital to get a professional generator maintenance report to manage the load testing procedure. If a generator is made to prolong operations at low loads, it can lead to permanent damage of the engine which will need a major engine overhaul. The costs of an overhaul can run high and so, replacing the unit altogether is the more economical option.

Rating your diesel generator right.

Ratings for a diesel generator is result of intended use and the ability to supply power. So, when you look at buying a generator, you would first consider its intended use. While it may seem obvious what power rating is required for an application but there are a number of factors to consider before purchasing a generator. Let’s familiarize ourselves with generator ratings and their relevance.

Standby Power Rating

The primary application of a Standby Power Rated generator is to supply emergency power for a limited duration during a power outage. These generators do not have an overload capability built into the units. Standby power rating should be applied to the unit where public utility power is available and power cuts are very rare.

Prime Power Rating

The prime power rating is the maximum power accessible at the variable load for an unlimited number of hours per year in a variable load setting. Prime power rated generators should be used if the public utility power is intermittent with frequent power cuts.

Continuous Power Rating

Continuous power rating is used in applications where the need for supplying power is at a constant 100% load for an unlimited number of hours each year. These units are used in applications where the power grid is unreachable, for e.g.: mining, agriculture or military operations.

Elevations and Temperature’s Effect on Power Rating

Beyond the above mentioned considerations, elevation and temperature are also factors to be considered before rating the engine.

Effects of Power Outages.

A common hurdle faced by India towards its growth factor is power outage. India is among the fastest developing countries of the world and so, it’s dependent upon the electricity sector to harness its growth. India is the third largest electricity producer and fourth largest in terms of consumption in the world. (Source) But unfortunately, an estimated 27% of the energy generated either gets lost or stolen during transmission. The peak supply falls short among 9% of the population. And what’s worse, frequent power outages last for as long as a whopping 10 hours. One of the biggest power outages that occurred in India was in the year 2012 when three grids i.e. northern, eastern and north-eastern had collapsed. This incident turned 22 states of the nation in shambles. And, this blackout wasn’t the first in that scale. The northern grid of India had fallen back in the year 2001, and the north-eastern grid blackout occurred in 2003.  The ripple effects of these incidents compelled the Indian government to take instant corrective measures.
Meghalaya, Andaman & Nicobar, Bihar, Tamil Nadu, Uttar Pradesh, Andhra Pradesh, Jammu & Kashmir, are among states that are most affected due to power cuts. Power shortages are more prominent in Odisha, Tamil Nadu and Andhra Pradesh while Maharashtra, Gujarat and Karnataka face minimum problems vis-à-vis electricity supply.

Power shortage has been among the most prevalent issue in India’s growth track. In fact, since 1951, India has missed every annual target to electricity production capacity, as per a Bloomberg report.

How do power outages affect the people?

§        Agriculture is a dominant factor in people’s lives in the rural areas with over 70% of the rural population depending upon electricity for irrigation, storing of allied products and sowing. Impending power outages affects rural households staggeringly.

§       Transportation system in urban life depends to a great extent upon electricity. From train services to automatic signaling system, electricity plays a major role. Power cuts do mess up the system.

§       The healthcare industry is badly disrupted by power outages. Lifesaving equipment cannot run without power and major operations stand cancelled. In such cases, DG sets are life saviors.

§         Data centers and IT industry processes come to a halt.

§       The lives of hundreds of workers in the mining industry is jeopardized.

§        Not to mention, everyday lifestyle of India’s population which is ever increasing is adversely affected in terms of computer shutdown, electrical equipment such as heaters and induction cookers fail to work and thus, productivity slows down.

How do power outages affect businesses?

§        Due to high frequency of power cuts, out of a total of 650 industries of various sizes surveyed, 61% companies face more than 10% of loss in production.

§        Infrastructure such as telecommunication networks, healthcare amenities, financial services, water supplies, transportation industry and mining companies get badly hit. The infrastructure constraints brought in by power outages in India increases the relative cost of carrying out businesses which in turn gives birth to supply side bottlenecks.

§        Frequent power outages gone unattended limit the private sector’s global competitiveness. As a result of this, fiscal conditions decelerate substantially.

§       The manufacturing industry chiefly depends upon electricity for production. Due to power cuts, machines and other multiple operations come to a standstill. This stops production from individual scale to batch scale altogether. The manufacturing sector is the backbone of India’s commercial success, and this disadvantage keeps India from making it to the top League of Nations.

Difference Between Blackout and Brownout.

When it comes to electricity flow, things aren’t black and white always. However, they can be termed as black or brown. It is possible that you know of a blackout in the past, but have you experienced a brownout? And what is the difference between the two phenomena?
A blackout can be defined as a complete loss of power affecting many users of electricity spread throughout a large area over an extended span of time. Residents and businesses lose electricity power and the entire area experiences a blackout.

A brownout is bit different in the sense it is a somewhat measured power reduction or loss of electricity to pockets of consumers. Brownouts can be caused due to the state of ‘poor power quality’ in which utilities may reduce line voltage to deliver more electricity for increased power demand. Factory equipment that requires a stable supply of energy can be severely damaged or even destroyed due to these voltage fluctuations.
Brownouts can cause issues with electrical devices that function on certain specific voltage levels, like computers. On the other hand, blackouts denote major equipment failure or weather related issues leading to a complete loss of electric power.

Sometimes, rolling blackouts are put into place by power companies to balance out an increase in power demand that cannot be met by the existing system output. The demand for electricity can be increased by heat waves and prompt the requirement for a rolling blackout.

HOW CAN YOU PREVENT THESE VOLTAGE FLUCTUATIONS?

Sadly, there are only a few ways to avoid this situation. In case you absolutely need to keep your equipment running always, you could consider power backups.
An intense upsurge in electricity demand does not occur often, but if you want to ensure that your business is geared for any possible threats, it is worth investing in dg sets lest you may be left out in the dark.

The Causes of Power Failures

Within a short span of two centuries, electricity has become indispensable to our day to day lives. Be it official work, entertainment, economy, healthcare or even simple activities of our livelihoods, we are totally dependent upon the constant supply of electrical power. In such scenarios, even a temporary loss of electricity can affect us greatly. It may lead to a relative chaotic situation, monetary setbacks may be faced, there may also be a possibility of loss of life. Power stoppage can especially cause mayhem when it comes to life-support systems such as in hospitals and nursing homes or in co-ordination facilities like traffic control, railway stations and airports.

Fortunately, most life support facilities have power backup which takes over automatically in the case of a power outage. Power backup is also increasingly being utilized in corporate offices, mining, manufacturing, businesses, and now even in residential complexes with the growing dependence on computers and electronics in everyday lives. So, though loss of power in small scale settings may not be lethal, it can still result into loss of data, missed deadlines, decreased productivity levels and also cause loss of revenue.

Thus, it is very important to know about the possible causes of power failure in order to be armed at all times, to protect ourselves and our businesses from its ill effects. When we have identified all that can possibly go wrong, it would be easier to ensure that adequate safeguards have been put into place.
 
Shared below are some of the major causes of power failure: -

1.       Weather conditions :- 

Power failures are majorly caused due to weather conditions. Lightning, wind, rain, snow and even dust are the various natural phenomenon that can cause power failure. While it is very difficult to guard against major power failures caused due to natural calamities as floods and storms, it is relatively easier to safeguard electrical systems from water and dust. Water can lead to short circuits and power outages. The damage caused due to water in electrical circuits are pretty expensive and thus it makes sense to ensure protection from it. Electrical switchboards, wires, and circuits should be protected and not exposed to water. Dampness and excessive moisture can lead to serious damages. Living in areas with higher levels of humidity makes it important to invest in specially sealed circuit protection devices. 
Dust can also wreak havoc with electrical systems and lead to short circuits and power failures. Areas that are exposed to dust and sandstorms are in dire need to ensure that the electrical circuits are protected from dust exposure at all times. Sealed circuit boxes can be helpful in ensuring protection of your critical electrical equipment and prevent power failures.
Natural disasters have historically been the root cause of the world’s most severe power outages. Floods, tsunamis, earthquakes, windstorms, and other severe weather conditions can completely destroy critical power infrastructure and result in outages that leave extensive geographic regions without power for months.

 2.       Short Circuits :-

‘Short circuit’ is the most commonly used term to describe the cause of power failure. At the same time, the term is also most bandied about without understanding the meaning very well. So, let us explain what exactly is a short circuit.

Short circuit occurs when electric current travels along a path which is not the intended path for it in an electrical circuit. Due to this, there is an excessive electric current which damages the circuit, cause fire and even an explosion to the extent that it’s one of the main causes of electrical fires all over the world. 

3.       Blackouts:-

‘Blackout’ refers to a total loss of electrical power in a given geographical area. It is also the severe most form of power outage that can occur. Depending upon what is the main cause of a blackout, restoring power is usually a very complex task for utilities and power stations and, repair time frames greatly depend upon the configuration of the affected electrical network.







4.       Brownouts:-

A brownout refers to a drop in the power supply. It is called, ‘brownout’ as it leads to a drop in voltage which causes the lights to dim. Brownout is not a total power failure, but it can adversely affect your electrical equipment. Induction and three-phase electrical motors (like the ones used in industrial diesel generators) are at greater risk during brownouts as they can get overheated and their insulation can be damaged. In case your main power supply is inconsistent and you’ve been experiencing brownouts frequently, you must invest in power back up system like diesel generators. They will automatically take over and provide your equipment with necessary electrical power whenever the voltage drops.

5.       Power Surges:-

Power surges are a bane when it comes to electrical systems. It can rapidly overheat and thus damage expensive electrical equipment. Surge protectors and circuit breakers can readily provide the much needed protection from such surges.

6.       Electrical treeing:-

Electrical treeing affects high power installations like transformers and high power voltage cables. If there are any impurities and mechanical defects in the equipment used in high voltage installations, then it can lead to partial electric discharges in the equipment. The process of damaging manifests in a tree-like pattern and hence the name ‘electrical treeing’. If over a period of time it goes undetected, it can continually degrade the equipment and eventually result into a complete breakdown.
To combat electrical treeing, one must only use top quality materials designed to handle the electric load. Maintenance by trained engineers can also help to identify and fix electrical treeing before a major breakdown.

Other Causes:-

When animals such as large birds come into contact with electric lines, power outages are bound to occur. Additional causes of power failures are primarily man made. Example, road accidents and accidents at construction spots with power poles and lines, maintenance issues and human error.

Importance of Diesel Generators in Small Scale Industries !!!!

Owing to establishment of new industries, infrastructure development, and evolving business environment, continuous power has become one of the main challenges today.
There is widespread lack of grid connectivity and infrastructure growth in far-flung areas, growing electricity demand-supply gap, strong commercial growth along with power deficits in various parts of the country. Also, the number of telecom towers has risen tremendously. Due to all these reasons, DG sets have gained prominence in the small scale industries segment in India.

Points to consider:

Uninterrupted power supply

The main problem for small scale industries in the country is that in spite of their best efforts, power disturbances do arise. While some issues may be the outcome of problems within the industry, most are due to events that are outside and thus are beyond the control of the facility manager. Faulty distribution system, voltage sags, voltage spikes, blackouts and brownouts in the utility can all cause interruption in service.
A dg set can be of much help in such scenarios.

Small scale industries worst hit by erratic power supply

The power situation in the country has left various industries immobilized. In Bengaluru, scheduled power cuts for housing consumers has been started. At the same time, commercial and industrial consumers are bearing the brunt of unreliable power supply.
Micro and small industries are majorly affected. Processing industries like plastic, foundry and rubber, are the worst hit. When plastic is molded, it has to be melted. When power supply goes off, it turns hard again and the whole procedure has to take place one more time. Textile industry has also been overtly affected, as is the case with other continuous processing industries.

Regions with most demand for DG sets

High power deficits as well as rapid development and industrialization in southern part of the country like Bangalore, Chennai and Hyderabad has meant that they have the highest demand for diesel generators. The auto component and manufacturing industries in Tamil Nadu, IT industry in Karnataka, pharmaceutical and bio-technology businesses in Andhra Pradesh and service sector and general engineering in Puducherry and Kerala are among the major markets for dg sets in this region.
The western region has the second highest position in the diesel generator market in India as it houses the largest number of industries, including automobile, iron and steel, chemical and petrochemical, textiles, jewellery, pharmaceuticals and cement. Maharashtra and Gujarat constitute of the maximum share in driving dg set growth in western part of India. Even though the power deficit situation in the western region is decreasing with every passing year, the demand for diesel generators remain constant, because they are a reliable source of backup power.
The manufacturing sector is projected to fuel growth in demand for dg sets due to the flourishing auto component industry. By the end of 2016, India is also being projected to become the second largest steel producer in the world. This industry demands continuous power supply for machining, running processing units, resin molding, welding, pressing, and assembling.

Easy to install and to operate, easily available in the market and low space requirements make dg sets the most preferred choice.
