The Types of Generators
Generators are used for the
generation of electricity and they
ensure that most of the essential
appliances can be run whenever there
is a power outage. Generators of
different wattage capacities can be
used according to the needs of the
individual. The choice of buying the
right type of generator depends upon
a number of factors like the wattage
capacity, voltage ratings, fuel type,
fuel efficiency, noise level,
portability and price – a prudent
choice can only be made if you knew
what to look for.
Stand By – Standby generators
provide backup power in homes and offices and are permanently installed outside the
house or office building. They are plugged into the electric circuits or home wiring. – The
unit turns itself on and off automatically. They can automatically detect disruption in the
usual electric supply and begin supplying power within a few seconds. – Propane and
natural gas offer a safe, long-term fuel supply and are more environment friendly than
gasoline or diesel fuels. – Like any motor, a generator motor creates quite a bit of heat
and needs a cooling system to prevent overheating. Standby generators can be either air-
cooled or liquid-cooled. The major difference is that air-cooled systems are louder and
not quite as effective. Liquid cooled systems are quieter and more dependable – and also
more expensive to purchase and to maintain.
Portable – Portable generators are usually used in places where there is no power supply
such as construction sites, camps, etc. These generators are sufficient to run appliances
like televisions, refrigerators, sump pumps and furnaces. – Portable systems are wheeled
units that require to roll the generator outside, start it up, and hook it up to a power inlet
box Portable generators supply electricity to selected appliances through extension cords.
– They are fueled by gasoline, which can be difficult to store and transport during a
blackout. Carbon monoxide is always a concern in the safe use of portable generators. –
They are designed to be used for short periods of time only a few hours at a stretch. As a
result, they tend to be much smaller and less expensive.
A related aspect of generator motors is the speed at which they run, as measured in
RPMs. Generators made for the US market operate at one of two speeds: 1800 RPM or
3600 RPM. 1800 RPM motors will last longer and run quieter; 3600 RPM motors are
smaller and lighter.
