Phase Converters for Rural Applications

Three-phase motors can be satisfactorily operated with phase converters on single-phase power at full load and with good phase balance if the converter is properly selected and applied. The correct phase converter installation is important, and allowance must be made for the changes in the motor-torque characteristics which occur. Data are shown for the torque characteristics of a motor operated on two typical phase converters compared with three-phase operation and the effect of capacitance on the torque characteristics.
