HOW DOES A DIESEL GENERATOR WORK?

A diesel generator is a piece of equipment that turns the chemical energy contained in diesel into electrical energy. By combining a diesel engine and an AC alternator, it is able to do this. A gasoline tank, control panel, and radiator are usually included.

WHAT IS THE PURPOSE OF DIESEL GENERATORS?

The diesel engine spins the alternator, which produces an AC electrical current. This is used to supply electricity to electrical equipment. They can be employed in a variety of settings, including schools, hospitals, factories, and households. They can be utilized as the primary source of electricity or in the event of a power outage. There are four primary ratings for generators, which vary depending on the use. For standby applications, Emergency Standby (ESP) and Limited Time Power (LTP) are utilized, whereas Continuous (COP) and Prime Rated Power (PRP) are employed when used as a major source of power. The number of hours and the load factor constrain each rating.

When a generator is utilized as a backup, it usually has a Transfer Switch. This is a mechanical mechanism that prevents the generator and the mains power supply from being connected to the load at the same time. When mains power is available, connecting a generator at the same time requires appropriate controls in order to run both in parallel. Without this control mechanism, the generator could be severely damaged, resulting in fires. When the mains supply fails, connecting a generator to the grid without isolating it from the mains may back-feed the grid, potentially killing someone working to restore the mains supply and likely damage your generator when the mains supply recovers.

This is referred to as “Island Mode” when used as the primary source of power (for example, when there is no mains supply or when the mains supply is too poor to use). Multiple smaller units can be connected in parallel to meet larger power requirements via a process known as synchronization.

DO THEY NEED TO BE MAINTAINED?

Diesel generators necessitate routine maintenance at predetermined times. This varies by manufacturer, however the engine is usually the most vital component to be serviced. Engines typically require servicing after 250 or 500 hours, but the manufacturer determines the service schedule. If you compare this to a car travelling at 50mph or 80kph for 500 hours, that’s 25,000 miles or 40,000 kilometers!

A routine service would often include a thorough inspection, replacement of the air filter, oil filter, and fuel filter, as well as oil and some belts, such as the radiator fan belt and the charging alternator belt.

Maintaining your generator is critical to ensure that it provides the electrical power you require when you need it.
