I applied via Campus Placement and was interviewed in Sep 2024. There was 1 interview round.
(3 Questions)
- Q1. Difference between induction motor and synchronous motor
- Ans.
Induction motor operates on the principle of electromagnetic induction, while synchronous motor operates at a constant speed determined by the frequency of the power supply.
Induction motor does not require any external excitation to run, while synchronous motor requires a separate DC power source for excitation.
Induction motor has a slightly lower efficiency compared to synchronous motor.
Synchronous motor is used in ap...

- Q1. Losses in transformer
- Ans.
Losses in transformer refer to energy losses that occur during the conversion of electrical energy from one voltage level to another.
There are two main types of losses in transformers: copper losses and iron losses.
Copper losses occur due to the resistance of the copper windings and are also known as I^2R losses.
Iron losses, also known as core losses, occur due to hysteresis and eddy current losses in the transformer c...
- Q2. Power factor significance
- Ans.
Power factor is the ratio of real power to apparent power in an electrical system, indicating the efficiency of power usage.
Power factor is important for measuring the efficiency of electrical systems.
A high power factor indicates efficient power usage, while a low power factor indicates wastage.
Improving power factor can reduce electricity costs and increase system capacity.
Power factor correction devices like capacit...

Interview Questionnaire
1 Question
- Q1. Transformer work principal in matul induction
- Ans.
Transformers work on the principle of electromagnetic induction.
Transformers consist of two coils of wire 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.
The voltage in the secondary coil is proportional to the number of turns in the coil and the rate of change of the magnetic field.
Transformers are used ...
