For power factor correction, synchronous motors operate at
A)no-load and greatly over-excited fields
B)no-load and under-excited fields
C)normal load with minimum excitation
D)normal load with zero excitation

Question

Quizplus · Accepted Answer

Synchronous motors can be used for power factor correction when they operate at no-load and with their fields over-excited. This condition allows them to behave like capacitors, supplying reactive power to the system, thereby improving the power factor.
