Chambal Fertilisers And Chemicals Electrician Interview Questions and Answers

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors are commonly used in various applications such as industrial machinery, household appliances, and vehicles.

• There are different types of motors including AC motors, DC motors, and servo motors.

• Motors consist of a rotor, stator, and various components such as coils, magnets, and brushes.

• Examples of motors include electric

VCB stands for Vacuum Circuit Breaker, a type of circuit breaker that uses vacuum as the arc quenching medium.

• VCB is a type of circuit breaker that uses vacuum as the arc quenching medium.

• It is used to interrupt the current flow in case of a fault or overload in the electrical system.

• VCBs are commonly used in medium voltage applications.

• They are preferred over other types of circuit breakers due to their high reliabili

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Consists of two coils of wire (primary and secondary) wrapped around a core

• Primary coil receives electrical energy and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy to the secondary circuit

• Used to step up or step down voltage levels i

Types of transformers include power, distribution, isolation, autotransformer. Parts include core, winding, tap changer, bushing.

• Types of transformers: power, distribution, isolation, autotransformer

• Parts of transformer: core, winding, tap changer, bushing

• Power transformer is used for high voltage transmission

• Distribution transformer is used for low voltage distribution

• Isolation transformer is used for safety purposes

• A

ACB and VCB breakers are electrical devices used for circuit protection.

• ACB stands for Air Circuit Breaker and VCB stands for Vacuum Circuit Breaker.

• ACBs use air as the medium to extinguish the arc while VCBs use vacuum.

• Both breakers are used for circuit protection and can be found in power distribution systems.

• ACBs and VCBs have similar parts including contacts, arc chutes, trip units, and operating mechanisms.

AC and DC motors are types of electric motors used for different applications. AC motors run on alternating current while DC motors run on direct current.

• AC motors run on alternating current, which means the direction of current flow changes periodically.

• DC motors run on direct current, where the current flows in one direction consistently.

• AC motors are commonly used in household appliances, industrial machinery, and H...read more
