Question

Accepted Answer

Interview questions for Junior Engineer Production related to transformers, circuit breakers, and loads.

Transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
The function of a transformer is to step up or step down the voltage level of an alternating current (AC) power supply.
Types of transformers include power transformers, distribution transformers, autotransformers, isolation transformers, and instrument transformers.
11kV is generated at generation stations because it is a safe and efficient voltage level for long-distance transmission of power.
Circuit breakers are devices that automatically interrupt the flow of electrical current when a fault is detected in the circuit.
Types of circuit breakers include air circuit breakers, oil circuit breakers, vacuum circuit breakers, and SF6 circuit breakers.
Inductive loads are those that require a magnetic field to operate, such as motors and transformers. Capacitive loads are those that require an electric field to operate, such as capacitors. Resistive loads are those that resist the flow of current, such as heaters and incandescent lamps.
Transformers work by using two coils of wire, called the primary and secondary, that are wrapped around a magnetic core. When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil.
