Original practice questions
These are preparation examples, not questions attributed to this employer.
What is the principle of operation of a transformer? A transformer operates on the principle of electromagnetic induction and is used to change the voltage levels in an AC circuit.
Explain the difference between a synchronous and an asynchronous motor. A synchronous motor runs at a constant speed within its stable load range at a fixed supply frequency, while an asynchronous motor's speed varies with the load.
What are the types of power losses in a transmission line? Power losses in a transmission line include resistive (I²R) losses, corona loss and insulation/leakage-related losses; radiation is generally negligible for ordinary power-frequency line-loss analysis.
How does a PID controller work? A PID controller calculates an error value as the difference between a desired setpoint and a measured process variable, and applies a correction based on proportional, integral, and derivative terms.
What is the function of a rectifier? A rectifier converts alternating current (AC) to direct current (DC), which is essential for powering DC devices.
Describe the working of a circuit breaker. A circuit breaker is a safety device that automatically stops the flow of electricity in a circuit as a protection against overload or short circuit.
