What is the working principle of DG set?
The functioning principle of a diesel generator is actually based on the law of energy conversion. This law states that the energy can neither be created nor be destroyed but can only be transformed from one form to other. A diesel generator contains an engine that uses diesel for its functioning.
How does a diesel power generator work?
A diesel generator works like this: Air blows into the generator until it compresses and then diesel injects. The combination of compressed air and diesel fuel causes the air to combust, starting the generator.
What is the power factor of DG set?
0.8 power factor
Most of DG manufacturers mention0. 8 as the rated power factor of DG. But it doesn’t mean that DG must be operated at 0.8 power factor at all the time, rather it is the minimum limit on the power factor of the load which can be served by it without affecting its performance in the long run.
What is kVA DG set?
Kilowatts (kW) are used to measure the real electric power provided by the generator, which is used directly by appliances and equipment in the building. Kilovolt-amperes (kVA) measure the apparent power. This includes real power (kW), but also reactive power (kVAR) drawn by devices like motors and transformers.
Which coolant is used in DG?
Ethylene glycol coolant is supplied to engine block and cylinder head internal components, such as oil cooler and intercooler. Air is pulled through the radiator.
What is alternator in DG set?
The alternator also referred to as ‘genhead’ is that part of a generator that produces electrical energy from the mechanical energy supplied to it by the engine.
Why do we use 0.8 power factor?
This 0.8 power factor is not the load power factor. It is a nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output.
What is kW capacity of 10 kVA DG?
8 KW
With a power rating of 8 KW this makes it one of the best options available in the market.
What is the diesel plants capability range?
Explanation: Since the invention of diesel engine, diesel engine plants are finding increased application as either continuous or peak load source of power generation. Due to economy of operation DG plants are used to generate power in the range of 1 to 50MW capacity.
What is the meaning of AH in battery?
Amp hours
Capacity – Amp hours (Ah): Battery capacity is measured in Ah, or Amp-hours. As the name suggests this means how many amps the battery can deliver in an hour. For example, a 12V lithium battery with a capacity of 100Ah can deliver 100A to a 12-volt device for one hour.
