Welcome to the official blog of Mahindra Powerol.
Here we will discuss interesting articles revolving around power,light and energy. We will also share with you the latest developments in our business with respect to diesel generators,industrial engines,home inverters and batteries.
All of us enjoy electrical
appliances, be it domestic or commercial. But we tend to forget that there is
an underlying network of cables supporting the entire system. High technology
is involved in the making these cables, which makes them withstand tough
conditions for years.
We strongly believe that basic
knowledge about the cables are a must for them who own a genset. Choosing the
manufacturer recommended Power Cable for your genset is important. To save a
few bucks we are often tempted to use cheaper options which may lead to many
issues like the ones discussed below.
Undersized cable will generate
excessive heat which may melt the protective cover of the cable leading to
hazards like fire or electric shock.
In case there is a short
circuit, an undersized cable will not withstand the fault current. The cable
may melt, burn or even cause severe damage to connected equipment even before
any tripping mechanism may work.
Powerol recommends the use of
3.5 Core Armoured Power Cable for three phase and 2 Core Armoured Power Cable
for single phase gensets.
Let us understand what this
3.5 Core cables will have 3
stranded wires for R, Y, B Phases, with diameter X and one stranded wire for
Neutral with diameter X/2.
A 2 Core cable will have one
Phase wire and one Neutral wire of same diameter.
3.5 Core Cable
2 Core Cable
Construction of 3.5 Core and 2 Core Armoured
Weather Proof Coating :
Withstands every weather condition.
Steel Armour :
Provides the mechanical and tensile strength to withstand toughest conditions.
Extra Insulation :
Under the steel insulation this extra insulation lies.
Core Insulation :
Prevents short circuit. Insulation material should be XLPE if underground cable
Stranded Conductor :
These are the current carrying conductors.
RIGHT POWER CABLE
due to usage of undersized cables and loose thumbing causes most of the
electrical failures. Choosing the right size and type of Power Cable is a
critical technical decision. Consider every possible factors before making a
The size of
Power Cables (generally referred in Sq.mm) primarily depends on the Ampere
rating of the Genset. Copper is a better conductor compared to Aluminium, they
are the best material to be considered. For the same amount current lesser
diameter of Copper cable can be used compared to Aluminium cable. Downside of
using a Copper Cable is they are heavier and costlier than the Aluminium

Generators have been the unchallenged king in the field of backup power
generation since ages. Modern day diesel generators are technologically very
advanced and meets every stringent emission norm enforced by the Government. While
the Government is still pushing the limit for the quality of emission, the Diesel
Generator manufacturers are working continuously to make a more fuel efficient
and environment friendly products.
While the technology for Diesel Generators was progressing, Natural Gas
technology also came a long way and made significant inroads in the market.
Generators are very silent, ensures very low operating cost and most
importantly the emission from a Gas Generator contains ZERO Particulate Matter.
emission from Automobiles and Generators significantly contributes in the
production of harmful Green House Gases (GHG). The CO2 and N2Ogases hold back the heat which tries to go back to space from the surface
of the earth, this makes the atmosphere warmer. The carbon particles (commonly
described as Particulate Matter or PM) present in the emission absorbs a huge
amount of heat and makes the atmosphere warmer. This is one of the major causes
of global warming which is causing havoc worldwide.
(Source: Center for Climate and Energy Solutions)
These emissions make the air extremely harmful for our health. Quality
of air in all major cities in India are worsening steadily. Air Quality Index
(AQI) is a scientific method of measuring the air quality and currently Delhi
is topping the chart in India for having the worst quality of air, indicated by
a higher AQI number. Delhi is having the highest Particulate Matter pollution
in India and currently the city with 6th worst air quality in the
world, if the entire NCR is added then it is the 2nd worst city in
The Particulate Matter present in the emission gases are often denoted
by PM2.5 and PM10. The PM2.5 refers to the
particulate matter with a diameter less than 2.5 micrometres. These fine
particles are dangerous for our health. Due to their small size they can
directly enter our lungs. They can disturb our entire Respiratory System and
pollution is a global concern. There can’t be any excuse for inaction. Our
sincere commitment towards a greener future is articulated by the launch of
India’s first CPCB 2 approved Natural Gas
Genset. It offers ZERO PARTICULATE MATTER EMISSION which makes it an
environment friendly Generator.
Powerol is closely working with natural gas suppliers to provide gas
pipe lines at your premises. Piped Natural Gas supply will eliminate the need
of periodic refuelling and will ensure good quality of fuel.
We human beings have destroyed enough of this earth in the name of
development. The use of fossil fuel which gave us the power and mobility, literally
transformed our lives, but we did not use it responsibly. Our own invention for
human wellbeing is turning against us.
It is high time for us to act responsibly. The choices we make today
will decide whether we are heading for a greener future or a disaster.
Thankfully today we have green technologies and innovations at our
disposal which promises to protect the environment.
Powerol is dedicatedly working on green technologies like Natural Gas
Generators, waste energy management, Battery for Telecom Sites, Solar Power for
Telecom sites, and so on.
You can be a part of our green journey either by owning a green
technology product or by spreading the awareness. We are all ears to hear from
you. If you have any questions or need any guidance, feel free to contact us. We
will be happy to help you.
Calculating the power requirement and then determining
the suitable rating of generator you need is called as Generator Sizing.
This is the most important factor to consider before you decide to buy a generator.
The determining factor for generator sizing can be
answered by considering the followings:
event of a power outage, should the generator
run the entire building or just emergency loads?
be the peak demands during summer months?
§If you have
Motors, Compressors etc, what will be your starting load?
After you have considered the above, you need to
identify your electrical equipment (electrical load) and sum up their power
requirements. This process is also called as Load Calculation. There are
many free ‘Load
Calculators’ available on the internet. You may take help from a certified
electrician. If you are not sure, take help from our sales representatives,
they will be happy to help – it is FREE for you!!
WILL YOU PLACE THE GENSET?
The genset should be
located where it is accessible for maintenance and repair, and high enough to
keep the generator safe if there is water logging during monsoon. There
should be enough air flow to let the generator breath properly.
Factors like minimum distance from residential
buildings, silence zone near hospitals, fire hazards etc. should be considered.
Compliance with local guidelines is a must.
TYPE OF FUEL ARE YOU GOING TO USE?
The most common fuel types for generators
in India are Natural Gas and Diesel. Cost can be a factor when choosing between
a diesel or natural gas generator.
In case of natural
gas, the availability of the fuel source is important.
Local government regulations may dictate which fuel
types are available to your area.
WILL BE INSTALLING YOUR GENSET?
Only a competent, experienced and certified authority
should do the installation.You may choose the right agency through your trusted

YOU PLANNED FOR THE FOUNDATION?
arrives at your premises, a cement concrete foundation of adequate size should
be made ready. An inadequate foundation may lead to excessive vibration
resulting in poor performance of your generator.
Only a competent and experienced authority should make
the foundation for your generator.You can consult our representatives for any support and
guidance, they will be happy to help you.
TYPE OF ENCLOSURE TO CHOOSE?
Most generator manufacturer’s make generators
with a standard sound attenuated enclosure (which reduces the sound level). The
sound level will be around 74 db (to meet standard CPCB compliance).
Some area may have a regulation of minimum allowed decibel level.
For example, places near hospitals, VIP zones, silent zone, airports etc. The
target sound level will determine what type of generator enclosure you need to
We also offer Super Silent (54 db) variants of generators to
suite your needs.
WILL DO THE MAINTENANCE?
A Diesel Generator
or a Gas
Generator needs maintenance. Unlike a car, generators are often neglected.
To ensure that the generator runs during a power failure when you need it the
most, proper maintenance routine should be followed.

have a maintenance contract with the manufacturer.
YOU THOUGHT OF THE TRANSFER SWITCH?
Do you need a
If you want to power
just one AC and few lights you may use a power cord connecting the generator
and the appliances. For small generators
powering small loads this is a common scenario, you do not need a Transfer
Switch in such cases.
When you have larger
loads and your loads are connected to an existing power panel then you will
need a Transfer
Switch. The Transfer switch is the link between the power panel and the

generator only for emergency loads or for every load you have. This will
determine the ampere rating and design of the Transfer Switch. You can choose a
manual Transfer Switch or an Automatic Transfer Switch (costs more).

generator do not need additional cold starting kit. Our generators are engineered
to run for every weather condition within India.
When you call an electrician what does he check? How does he identify
faults in your electricity
supply lines? Do you have clear understanding of the Phase, Neutral and
Earth points in the sockets of your house?
Well, we are not trying to teach you Electrical Engineering. As a
consumer, it is smart to be aware of the electricity distribution
from Power Plant to your house. It is also important to understand the Phase –
Neutral – Earth points and what is their importance.
Let us first understand the basic of domestic electricity supply chain.
Domestic electricity supply can be broadly divided into three categories:
GENERATION:Generation happens in big power
plants (Thermal, Hydro, Nuclear, Solar, Wind etc)
is stepped up for ease of transmission. Power is transmitted via DELTA
connection, (a Delta connections needs only 3 wires R-Y-B).
DISTRIBUTION:From the transmission lines the power is stepped down through local transformers
and from the local transformer connection is distributed to individual houses.
From the local
transformers power is distributed to different houses as STAR connection
which is having 4 wires. Three Phase wires and one Neutral wire. The Neutral
point in the transformer is connected to the ground.
For domestic connections, the Neutral point is common, and any one
phase (R, Y or B) is given as line to individual houses.
Understanding the Socket
the left point will be Neutral (N) and the right point will be Phase (P). The
Earthing (E) point will be at the top. The earthing is used for safety purpose.
Point P should always have power, this can be checked by a Tester. The
N point has no power in it, it cannot be checked with a Tester. To check the N
point, a test lamp should be used.
What is the
difference between Earth and Neutral?
Neutral is connected to the Neutral point of your local distribution
The Earth point is unique, made for your house only.
Why Earthing is important?
If earthing is not done, there will be chances of electrical shock
in case there is some fault in the circuit.
No risk of electric shock if Earthing is done even if there is a fault
in the circuit.

Energy infrastructures across the world are
under stress and this could lead to a sudden and unexpected power
outage. While scheduled load
shedding can be prepared for, the unexpected outages can delay production and
even lead to massive losses.
Consistent power supply is mandatory if you need sensitive data.
generators typically switch on
within ten seconds of a power outage, a backup generator can save millions of
man hours and money.
