HOW DOES A POWER GENERATOR WORK?

A power generator is a vital piece of site equipment, whether on major construction projects or outdoor events, ensuring a continuous supply of energy. But how do they work?

THE BASIC PRINCIPLES

A generator converts mechanical energy (rotational engine movement) into electrical power via windings channelled into power cables. Many models have a diesel or petrol engine to produce the mechanical energy.

The details of how they work is a big subject, so we’d thought we’d keep it simple.

Imagine a generator acting like a pump, pushing water through a pipe, only instead of pushing water, a generator uses a magnet to push electrons along and applies a certain amount of pressure to the electrons.

In an electrical circuit, the number of electrons in motion is called the amperage or current, and is measured in amps. The "pressure" pushing the electrons along is called the voltage and is measured in volts.
