Aarvee Denims & Exports Electrical Supervisor Interview Questions and Answers

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

• Consists of two coils of wire, known as primary and secondary coils

• Primary coil receives electrical energy and creates a magnetic field

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

• Used to step up or step down voltage in power distribution systems

• Examples: power transfor

Transformer rating in kVA is used to indicate the maximum amount of power that can be safely handled by the transformer.

• kVA rating is used to determine the maximum amount of power that can be safely handled by the transformer.

• It helps in selecting the appropriate size of transformer for a specific application.

• kVA rating takes into account both the voltage and current handling capabilities of the transformer.

• Higher kVA ...read more
