Hps Air Systems Interview Questions and Answers

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers consist of two coils of wire wrapped around a magnetic core

• The primary coil receives electrical energy and creates a magnetic field

• The magnetic field induces a voltage in the secondary coil, which transfers the energy to the load

• Transformers can step up or step down voltage l...read more

DG stands for Diesel Generator. It is a backup power source used in case of power outages.

• DG is a standalone power source that runs on diesel fuel.

• It consists of an engine, alternator, fuel system, cooling system, and control panel.

• DG is used as a backup power source in case of power outages or in remote areas where grid power is not available.

• DGs are commonly used in hospitals, data centers, and other critical facilit...read more

A motor is an electrical machine that converts electrical energy into mechanical energy.

• Parts of a motor include stator, rotor, bearings, and shaft.

• The stator is the stationary part of the motor that contains the coils of wire.

• The rotor is the rotating part of the motor that contains the magnets.

• Bearings support the rotor and allow it to rotate smoothly.

• The shaft connects the rotor to the load being driven.

• Functions of...read more

Circuit breakers are safety devices that automatically interrupt electrical flow when a fault is detected.

• Circuit breakers protect electrical circuits from damage caused by overcurrent, short circuit, or ground fault

• Types of circuit breakers include thermal, magnetic, and hybrid

• Thermal circuit breakers use a bimetallic strip to trip the breaker when it gets too hot

• Magnetic circuit breakers use an electromagnet to trip ...read more
