IS IT DIFFICULT TO INSTALL?
No, it is the easiest of all types to install, comparable
to installing any electric motor. A disconnect switch or magnetic starter
is needed to start the converter and the single phase wiring must be
adequate to handle the current of all the motors to be operated. It must
be emphasized that our wiring recommendations should be carefully followed.
How does a rotary three
Phase Converter compare with a solid three phase line?
A three Phase Converter is a manufactured device that
comes closest to a solid three phase line. In comparison to an open delta
three phase system the three Phase Converter is equal and every bit as
Against other solid three phase systems, a three Phase
Converter is merely the best substitute. Never-the-less, a solid three
phase is often not economically feasible nor readily available. For short
seasonal loads or small loads, it is generally impractical.
The three Phase Converter cost is often just a fraction
of the cost of extending a three phase line, whether a few hundred feet
or many miles. Cost of operation on a single phase line is invariably
less than on solid three phase. Rate costs are less, with no demand or
power factor penalties.
Three Phase Converter, being a rotary type, is a three-
phase distribution system in which a variety of motors can be operated
individually or simultaneously, just as though connected to a three phase
As three Phase Converter is rotating, a phase shift
is accomplished through a rotor spinning within an electrical field.
The result is a true three phase.
An Indiana power company's three year study revealed
that corn was dried at less than 1/2 cent per bushel electrical cost.
Their study also revealed that no single phase motor or three phase drying
installation had a per bushel electric cost as low as this.
