Generators voltage output ranges from hundreds of
volts to 30,000 volts. This can be from small portable
3 phase generators, 3
phase generating rotary converters, or utility
power stations. At the power station, transformers
step-up this voltage to one more suitable for transmission.
Popular Generators Fuel Includes Propane & Diesel
Generators
3 phase
power generators
can be purchased to run on a variety of fuel types
including two of the most popular: propane and
diesel
generators.
Because of the common availability of propane, natural
gas and diesel fuel, there are also a wide variety of
generators built specifically to use these fuel types.
After
numerous further conversions in the transmission
and distribution network the 3 phase power is
finally transformed to the standard mains voltage (the
voltage of "house" or "household"
current in American English). The power may already
have been split into single phase at this point or it
may still be 3 phase. Where the step-down
is 3 phase, the output of this transformer
is usually star connected with the standard mains
voltage (120V in North America and 230V in Europe)
being the phase-neutral voltage. Another system
commonly seen in the USA is to have a delta connected
secondary on the step
down transformer with a center tap on one of the
windings supplying the ground and neutral. This allows
for 240V 3 phase as well as three different single
phase voltages (120V between two of the phases and the
neutral, 208V between the third phase (sometimes known
as a wild leg) and neutral and 240V between any two
phases) to be made available from the same supply.

Phase Loads
The
most common class of 3
phase load is the 3
phase electric motor. A 3 phase induction motor
has a simple design, inherently high starting torque,
and high efficiency. Such motors are applied in
industry for 3
phase pumps, fans, blowers, compressors, conveyor
drives, and many other types of motor-driven
equipment. A 3 phase motor is more compact and less
costly than a 1-phase motor of the same voltage class
and rating; also 1-phase AC motors above 10 HP (7.5
kW) are not as efficient and thus not usually
manufactured.
Large
air conditioning equipment (for example, most York
air conditioning units above 2.5 tons (8.8 kW) cooling
capacity) use 3 phase motors for reasons of economy
and efficiency. Read more about 3
phase power loads here.

Phase Loads from 3 Phase Power Generated on 1 Phase
Power
There
are many places and instances where 1 phase power is
all that is available, or where the power company
wants to charge tens, or even hundreds of thousands of
dollars to install and supply 3 phase power.
When this is the case a quality 3
phase generating phase converter can be run on 1
phase to power 3 phase equipment of any type.
