How do Generators Work? Working – Parts – Types – Advantages

Most people are confused about the working of electric power generators. Because everyone is not electrical engineer. Today I am going to tell you how do generators work?.

To make it more helpful and easy, I will try to not use any technical language in this guide. I will try to explain all the basics about generators and how do power generators work in very easy and learnable way.

Electrical generator is a machine that converts chemical energy or mechanical energy into electrical energy.

After completely understanding the mechanism of working of generators, must lean about safety tips and maintenance of power generators.

How do Generators Work? Simple Guide

Electrical Generators don’t create electricity themselves. In fact, they convert mechanical energy into electrical energy.

How does a Generator Create Electricity?

For better understanding, let’s discuss how do generators produce electricity… (check flowsheet here)

  • First generator gets mechanical energy from a source (fossil fuels, turbines, waterfalls, etc.)
  • Then this mechanical energy excites the electrons or electric charges present in the wires of the generator.
  • Now the electric charges start flowing through the wires of the generator. This flow of electric charges produces an electric current.
  • Generators supply this electric current to the power cables of domestic, commercial, or industrial consumers.

If you understand the working of generators then don’t forget to read the guide about “how to ground a generator?”

Main Parts of Electrical Generator

  • Frame: Body Structure of the generators
  • Control panel: A panel composed of Buttons and switches which control all operations of the generator.
  • Battery: The battery keeps the charging system of the generator up to a mark. It needed to start up the generator.
  • Fuel System: They are sources of gas or diesel. This system sends the gas or fuel to the engine.
  • Engine: The engine supply mechanical energy to the generator.
  • Alternator: They convert mechanical energy into electrical energy or electricity.
  • Voltage Regulator: They control the voltage of the system and convert AC – DC.
  • Exhaust System: They cooled down the generators and control the overheating of generators.

What is the difference between AC & DC Current?

  • AC Current: Alternating Current (AC) is a two-way current it can go/supply in any direction.
  • DC Current: Direct Current (DC) is a one-way current it can go/supply in only one direction.

AC power is used for high voltage appliances while DC power is used for low voltage appliances. Do you know about grounding a generator during camping? if not then read it here; “how to ground a generator during camping?

What are the Advantages of a Generator?

  • Generators provide electricity continually when there is no electricity during construction, blackout, disasters, hurricanes or any other emergencies.
  • It allows more mobility and time independence in your business.
  • It increases the value and indoor quality of your home.
  • Buying a generator is a safe investment that pays off.

Final Verdict

In this complete guide about “how do generators work?” you have learnt all the basic of the workings of generators. Now you can tell or teach the basics of how a generator makes electricity.

How does a generator create electricity?

A turbine generator is a machine that converts the mechanical energy from moving fluids into electrical output.

The heart of this amazing piece of machinery are blades made up of steel or titanium, which spin at high speeds as water flows past them on either side, pushing it forward with great force – turning all those mechanical energies into electricity for our homes!
