| FAQs |
| |
| Where can Gensets
be used? All places where electricity is required
are suitable applications for using Gensets. |
|
|
|
What does a Genset consist of ? A
Basic Genset consists of an engine and an alternator coupled to each other and
mounted on a common base frame along with batteries, fuel tank, manual control
panel and silencer. |
|
|
|
Which are the various types of fuels that can be used
? As a general rule, Gensets below 1500kVA can
run only on High Speed Diesel. Special 1500 RPM engines are available for alternate
fuels like natural gas and also for dual fuel applications where a combination
of diesel and gas can be used. For heavy fuel application (LDO, furnace oil, LSHS)
low RPM engines are available and these and generally of higher ratings, i..e
0.7 MW and above. These Genest installations are much more expensive than 1500
RPM sets. They are installed at locations where continuous power is required.
Bio gas, wood gas, gobar gas, etc., are not directly compatible for use with our
engines. |
|
|
|
What are the required approvals to run a Genset ?
To install and run a Genset, permission is required from the following authorities
: |
 |
Local Electricity Board - In most States,
it is necessary that the Genset capacity should be equal to or less than the sanctioned
load for the location at which it is being installed. |
 |
Electrical Inspectorate - This approval
is required as it confirms that the installation, cabling, earthing, etc., have
been carried out as per the Central Electricity Rules applicable to all electrical
applications in India. |  |
Central Pollution Control Board - For obtaining
this approval, the exhaust gases of the Genset have to be discharged at a particular
height above the building housing the Genset, so that the exhaust does not cause
pollution. | |
| |
| Which are the
various types of panels available ? A standard
Genset is usually supplied with a manual control panel. In this case, the engine
is started from it own control panel and after the rated speed and voltage have
been attained the switch in the manual panel is put on to connect the Genset to
the load. |
| |
| For special applications
various other panels can be made to order and some of these are as follows: |
 |
AMF application: In these panels, the mains/
Electricity Board supply is monitored and in case of failure the Genset will start
automatically and the load will be transferred to the Genset. When the Mains supply
is restored, the load will be transferred back and the Genest will be shut down
after a short cooling down period. AMF panels can be relay operated or PLC operated
and options of auto start, auto changeover, no break change over etc. are also
available. |  |
Synchronising panels: In some cases it may
be necessary to run two or more Gensets in synchronism with each other. This may
be required due to various reasons like high start-up loads, major variations
in load during peak / non-peak hours, limitation in capacity of gensets etc. For
these kind of applications, synchronising panels can be provided. These can be
simple or very sophisticated viz. fully automatic depending on customer needs.
| |
| |
| Where are Acoustic
Enclosures required ? Due to the increasing emphasis on pollution of
various kinds affecting citizens it has become mandatory in most major cities
for all new genset installations to be provided with some kind of noise reducing
systems. This can be either achieved by providing acoustic treatment to the walls
of the DG room or by installation of an Acoustic Enclosure over the Genset. Both
options are available and the feasibility at each location has to be checked and
the best option selected. |
| |
| Who does the installation
and what are the prerequisites ? Installation of Gensets can be carried
out by end user / his contractor or by Power Engineering (India) Pvt. Ltd. Necessary
guidelines and drawings for the installation of various auxiliaries and accessories
will be provided by us. Commissioning of the Genset after installation has to
be carried out by PEC engineers, to ensure that the installation meets the necessary
engineering standards. |
| |
| Who takes care
of after sales service ? PEC has offices where service engineers are
available to attend to any problems that you may face with your genset. M/s.Kirloskar
Oil Engine Limited also has a network of 180 dealers and offices all over India
and these offices will provide after sales service for both engine and alternators
installed in their areas. |
| |
| What is the applicable
guarantee for the genset ? The engine and alternator
are guaranteed for 24 months from the date of commissioning or 5000 operating
hours whichever is earlier. |
| |
| What spares should
be stocked ? Since there is a large network of dealers all over India,
necessary routine maintenance spares do not need to be stocked by the end user,
these are readily available. Failure of any major equipment will require the engine/alternator
to be either repaired at site by qualified engineer /technicians or will have
to be shifted to the closest authorised service dealer. Even in this case no spares
need to be stocked by the end user. Minor items like indicating lamps, fuses,
top-up oil, grease, etc. are available with the maintenance team at factories
or can be procured from the closest hardware store. |
| |
What is the general maintenance schedule
? All filters, fuel, lub oil, bypass, etc. along with lub oil have to
be changed after every 250 hours of operation or six months, whichever is earlier.
Besides this, the general daily, weekly, and monthly checks are to be carried
out. |
| |
| What are the guidelines
for understanding specific rating of the DG Sets ? STANDBY POWER RATING: |
| Applicable for supplying
emergency power for the duration of the utility power outage. No overload capacity
is available for this rating. Under no condition is an engine allowed to operate
in parallel with the public utility at the Standby Power Rating. |
| |
|
This rating should be applied where reliable utility power
is available. A Standby rated engine should be sized for a maximum of an 80% average
load factor and 200 hours of operation per year. This includes less than 25 hours
per year at the Standby Power Rating. Standby Ratings should never be applied
except in true emergency power outage. Negotiated power outages contracted with
a utility company are not considered an emergency. |
| |
| PRIME POWER RATING: |
| Applicable for supplying
electric power in lieu of commercially purchased power. Prime Power Applications
must be in the form of one of the following two categories : |
| |
|
UNLIMITED TIME RUNNING PRIME POWER CONFIRMING TO IS 10002. |
 |
Prime power is available for an unlimited number of hours
per year in a variable load application. |
 |
Variable load should not exceed a 70% average of the Prime
Power rating during any operation period of 250 hours. |
 |
The total operating time at 100% Prime Power shall not exceed
500 hours per year. |  |
A 10% overload capability is available for a period of 1
hour within a 12 hour period of operation. |
 |
Total operating time at the 10% overload power shall not
exceed 25 hours per year. | |
| |
| LIMITED TIME RUNNING PRIME POWER: |
 |
Limited time Prime Power is available for a limited number
of hours in a non-variable load application. It is intended for use in situation
where power outages are contracted, such as utility power curtailment. |
 |
Engines may be operated in parallel to the public utility
up to 750 hours per year at power levels never to exceed the Prime Power Rating.
|  |
The total operating time at 100% Prime Power shall not exceed
500 hours per year. |  |
A 10% overload capability is available for a period of 1
hour within a 12 hour period of operation. |
 |
Total operating time at the 10% overload power shall not
exceed 25 hours per year. | |
| |
| CONTINUOUS POWER RATING:
|
| Applicable
for supplying utility power at a constant 100% load for an unlimited number of
hours per year. No overload capability is available for this rating. |
