How Does A Standby Generator Work?

A standby generator is designed to provide power when there is a disruption to the mains power supply.

How does a standby generator work?

A diesel standby generator uses diesel as its fuel source. Diesel burns at a much higher temperature making it more powerful and efficient.

  1. First, air is propelled into the generator until it is compressed and then diesel is injected
  2. The combination of these two processes generates the heat that triggers the fuel to ignite
  3. The combustion of the diesel starts the generator, making the central shaft move, and transforming the mechanical energy into electrical power, with the help of the alternator;
  4. As a result, the generator starts producing the necessary electrical energy to be distributed until the mains power supply returns.

Standby generators can be run for long periods of time, as long as it is correctly maintained, and fuel is in the best condition as possible.

When paired with an automatic transfer switch, the power will automatically transfer the power supply from the primary source of power to your standby generator when it detects a failure or outage.
