What is a Generator?

A generator set is an electric machine consisting mainly of a motor (mostly diesel or gasoline), an alternator and an electrical control panel. It serves to supply electrical energy, when a power failure occurs or in isolated places where there is no mains supply.

How does a Generator work?

A generator set is a rotary electric machine that transforms mechanical energy into electrical energy. Thanks to the engine and the alternator, they achieve through the interaction of the two elements, convert the mechanical energy into electrical.

The alternators generate electricity in alternating current through a moving part called a rotor, which will rotate by the mechanical force exerted by the motor, and a static part called the stator.

There are three main types of generators: portable, inverter and standby. Despite their differences, all of these generators should undergo similar generator maintenance to ensure long-term use.

1. Portable Generator

A portable generator is powered by gas or diesel fuel and can provide temporary electrical power.

Here are some characteristics to note about these types of generators:

  • Uses a combustion engine to conduct electricity.
  • Can plug into electrical appliances or tools via its sockets.
  • Can be wired into a facility’s subpanels.
  • Can be used in remote sites.
  • Has enough power to run a television, freezer and refrigerator.
  • The engine should run at 3600 rpm to render the standard 60hz of current.
  • Use a governor to control the engine’s speed.
  • Can power tools and lights.

2. Inverter Generator

An inverter generator uses an engine connected to an alternator to produce AC power. It also uses a rectifier unlike other generators to convert the AC power into DC power.

Here are some characteristics to note about these types of generators:

  • Relies on high-tech magnets.
  • Uses advanced electronic circuitry.
  • Undergoes three phases to produce electricity.
  • Outputs AC current, convert it to DC current and finally invert it to AC.
  • Maintains a constant flowing of current to an appliance.
  • Is more energy-efficient, as the engine speed adjusts itself according to how much power is needed.
  • Its AC can be set to any voltage and frequency when used with proper equipment.
  • Tends to be little and lightweight.
  • Can fit into a car, RV or boat.

3. Standby Generator

A standby generator is an electrical system that operates with an automatic transfer switch that commands it to power a device up during power loss.

Here are some characteristics to note about these types of generators:

  • Operates automatically.
  • Delivers permanent power protection.
  • Has two components: a standby generator and an automatic transfer switch.
  • Can operate on liquid propane or natural gas.
  • Will run on the fuel type already in use in the facility or home.
  • Uses an internal combustion engine.
  • Senses the power loss within seconds and boots up electricity so that power loss is felt very briefly.
  • Executes automatic weekly self-tests to see that it is properly reacting to a power loss.
  • It is constantly monitoring utility power.
  • Used in safety systems for elevators, standby lighting, medical and life support equipment and fire protection systems.

Frequently Asked Questions About Generators

1. How Long does a Generator Last?

A properly cared for generator can last decades, which means in the long run, having a generator will save you money in addition to restoring lost power. Standby generators tend to need a lot of regular maintenance, especially when it is used for long periods of time. With regular inspection, you will be able to replace worn out parts, clean out filters, and keep your generator in top condition.

2. What happens if i use a generator below capacity

All engines are designed to work under different load conditions, from maximum to minimum. Problems occur when the engine runs at low loads (minimum load) for a long time, causing it to not reach its normal temperature. The oil that is normally burned in the cylinder will heat up forming a layer of sediment in the cylinder liner. If low loads continue to work, blue smoke will appear and the engine will need to be serviced to remove the sediment layer from the jacket or to replace it.

3. Do Generators Need Maintenance?

Just like any other mechanical equipment, generators also need to be maintained in order to prevent permanent damage and keep your unit in proper working order. Just like a car engine, generators require periodic filter and oil changes, so check your user’s manual for recommended maintenance intervals and procedures. It is also a good idea to do a test run of the generator each month to prevent blockage in the carburetor and to avoid any surprises so that the unit is ready for when you need it.


Both standby generators and portable generators offer different benefits for homeowners to consider when making their purchasing decision. The main difference between standby and portable generators is the manner in which power is transmitted into your home along with the electrical capacity.
