GAIL Graduate Apprenticeship Trainee Interview Questions and Answers

The principle of a generator is based on electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.

• Generators convert mechanical energy into electrical energy

• They work on the principle of electromagnetic induction

• A rotating coil within a magnetic field generates an electric current

• The direction of the current is determined by Fleming's right-hand rule

A current transformer is a type of instrument transformer that is used to step down high currents to a lower, more manageable level for measurement or protection purposes.

• Current transformers are typically used in conjunction with ammeters, wattmeters, and protective relays.

• They have a primary winding that is connected in series with the circuit carrying the current to be measured, and a secondary winding that is conne...read more

The principle of motor refers to the basic concept of how motors work to convert electrical energy into mechanical energy.

• Motors operate based on the principle of electromagnetic induction

• Electric current flowing through a wire creates a magnetic field

• This magnetic field interacts with other magnetic fields to produce motion

• Motors can be DC motors, AC motors, or stepper motors

Speed and frequency in a motor are directly proportional to each other.

• Speed of a motor is directly proportional to the frequency of the power supply.

• Increasing the frequency of the power supply will increase the speed of the motor.

• Conversely, decreasing the frequency will decrease the speed of the motor.

• This relationship is important in controlling the speed of motors in various applications.
