WHEN TO USE PHASE CONVERTERS

The use of a phase converter is the best choice when:

1. The cost of the line extension to bring three phase power to the prohibitively expensive.
2. The cost per kilowatt hour for three phase service is substantially higher than single phase service.
3. You need a large motor but the starting current of a standard single phase motor is too high.
4. You need temporary three phase service until regular three phase service becomes available.
5. You purchase equipment with a three phase motor as an integral part of the unit and replacement of the motor is either too difficult or costs more than a converter.
6. You need a number of motors and the cost of three phase motors, plus converter, is less than the cost of the single phase motors.

TYPES OF PHASE CONVERTERS

Static and Rotary phase converters.  Each type offers advantages for different applications and is chosen depending on the loads.  The variations in design between the different types can make a difference in motor performance, particularly in such important factors as motor starting torque and temperature rise.  The engineering staff at TP Electric and Manufacturing are always available to assist you in selecting the proper unit.
