Frequency relays have the advantage that an increase in motor load prolongs the starting time.

Question

Quizplus · Accepted Answer

Frequency relays sense the frequency of the motor and adjust the starting time accordingly. As the motor load increases, the frequency decreases, and the starting time is prolonged to avoid overloading the motor. Frequency relays monitor and control the frequency of the electrical supply to the motor. An increase in motor load causes a drop in frequency, and the frequency relay will extend the starting time to ensure that the motor is not overloaded at startup.
