What is a Generator?

A generator is a powerful unit that converts mechanical energy to electrical energy. Generators use diesel, propane, and gasoline. They convert this fuel supply into electric energy that you can use to power a wide range of devices. 

 

During power outages, a generator is the primary source of electrical supply. Besides, generators provide safe backup power in hospitals, schools, industries, businesses, and many more areas. 

 

There are multiple generators in the market, and you can buy one for any need. In addition, you can find the small, portable ones suitable for outdoor use to offer portable devices that do not require much power. 

 

Others are designed to be installed permanently to power an entire house. Still, industrial generators are strong enough to power a facility, hospital, layout office, school, and many more areas that require adequate power. 

 

There are different types of generators: portable generators, inverter generators, and standby generators. They all have one primary purpose: to offer reliable backup power in case of an emergency. A generator can provide years of use when you do the following:

 

  • Checking the cooling system every time, mostly during shutdown periods 
  • Annual fuel filtering and cleaning 
  • For standby generator, keep checking for the battery’s health 
  • Do regular testing to know the battery’s current status
  • Keep records of tests for future inspections.


How Does a Generator Work? 

Generally, a generator does not create electricity. Instead, it converts mechanical or chemical energy from propane, gasoline, diesel, biogas, or LPG into electrical power.

 

A generator has an engine that rotates the axle of an electric conductor in a magnetic field which creates reliable power. For a generator to work effectively, it must have the following components. The components include: 

 

  1. Alternator 

An alternator is an important device that converts mechanical energy into AC electrical energy. It has both stationary and moving parts that combine to create a magnetic field and the movement of electrons that generate power. 

 

  1. Engine 

The engine is the component that supplies energy to the generator. An engine’s size and design determine the power a generator can provide by running on a specific fuel. An engine can be run on gasoline, liquid propane, diesel, propane gas, or natural gas. 

 

  1. Fuel System

A fuel system helps the generator produce the amount of energy required. Most generators have a fuel system with enough capacity to run the generator for about 6 to 8 hours. For commercial use, you can install an external fuel system. A fuel system contains the following: 

 

  • An overflow connection from the fuel tank to the drain hose
  • An exhaust pipe for the oil tank 
  • A fuel pump 
  • Fuel water separator or fuel filter 
  • A fuel injector

 

  1. Cooling System 

Generators create a lot of heat, and they need to cool every time. This system prevents the generator from overheating by extracting the heat. Many coolants are used, such as fresh water and hydrogen. A generator should have fans and radiators as the primary cooling system for residential and industrial use.

 

  1. Voltage Regulator 

This component regulates the voltage produced. It helps balance the current while still ensuring your devices are safe. When the generator entirely operates, the regulator goes into equilibrium and has adequate DC to maintain the output in the entire operation. 

 

  1. Lubricating System 

A generator contains many moving parts. They need regular lubrication to perform effectively. Consider lubricating the engine regularly using the oil stored in the pump. Keep checking the lubricant level after every 8 hours of the generator’s application. Check and replace lubrication oil leaks every 500 hours of the generator’s operation. 

 

  1. Battery Charger 

A generator relies on batteries to startup. The role of a battery charger is to keep the generator’s charger charged by supplying accurate float voltage. The float voltage should be accurate to prevent low charging or shorten the battery life when the float is too high.

 

Battery chargers are made of stainless steel to avoid corrosion and perform well. No adjustments or changes to the settings are needed because it is automatic. 

 

  1. Control Panel 

A control panel monitors everything from startup, running speed, controlling power outage to shut off. In addition, a control panel contains engine gauges, battery voltage, rotational speed, and working period.

 

A panel includes a meter that measures the output current, operating frequency, and voltage. Some other controls include frequency switch, phase selector switch, and engine control switch. 

 

  1. Frame Assembly 

This is the main body of a generator. The custom case offers a structural support base, allowing grounding for safety.
