Electrical Field Engineer Interview Questions and Answers

Transformer protection is a system that ensures the safe and reliable operation of transformers.

• It involves monitoring and controlling various parameters such as temperature, oil level, and pressure.

• It also includes protection against overloading, short circuits, and earth faults.

• Different types of protection devices are used, such as relays, fuses, and circuit breakers.

• Proper transformer protection helps to prevent damage to the transformer and ensures uninterrupted power su...read more

Transformer works on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.

• Transformers have two coils, primary and secondary, which are wound around a common magnetic core.

• When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.

• The voltage induced in the secondary coil is proportional to the number of turns in the coil and the rate of change of the magn...read more
