Question 230Electricity/Electronics - Assistant Engineer70% to pass
Occasionally a synchronous motor is configured without an external shaft to drive a load. In this case, the sole purpose of the synchronous motor is improving overall power factor of an electrical distribution system. What is the name of the synchronous motor so constructed?
AI Explanation
The correct answer is D) Synchronous condenser.
A synchronous condenser is a synchronous motor specifically configured without an external shaft to drive a load. Its sole purpose is to improve the overall power factor of an electrical distribution system by absorbing or generating reactive power as needed. This allows the synchronous condenser to compensate for lagging power factors and improve the efficiency of the electrical system.
The other options are incorrect because they do not accurately describe the specific configuration and purpose of a synchronous condenser. A synchronous compensator is a more general term, a motor-generator is a different device, and a synchronous converter typically refers to a device that changes AC to DC or vice versa.
