(2 Questions)
- Q1. AC Voltage And Frequency?
- Ans.
AC voltage and frequency are key parameters in electrical engineering, determining the power supply characteristics.
AC voltage is the amplitude of the alternating current signal, measured in volts.
Frequency refers to the number of cycles per second in the AC signal, measured in Hertz (Hz).
Standard AC voltage in most countries is around 220-240V at a frequency of 50-60Hz.
Variations in AC voltage and frequency can affect...
- Q2. DC Voltage And Frequency?
- Ans.
DC voltage is a constant voltage level, while frequency refers to the number of cycles per second in an alternating current.
DC voltage is a constant voltage level that does not change over time.
Frequency refers to the number of cycles per second in an alternating current.
DC voltage is typically used in batteries and power supplies.
Frequency is measured in Hertz (Hz).
(2 Questions)
- Q1. What's this AC Motors and DC Motors?
- Ans.
AC motors run on alternating current while DC motors run on direct current.
AC motors change the direction of current flow periodically, while DC motors maintain a constant direction of current flow
AC motors are commonly used in household appliances and industrial applications
DC motors are often used in battery-operated devices like toys and electric vehicles
- Q2. What's this Transformers?
- Ans.
Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Transformers consist of two coils of wire, known as the primary and secondary coils, which are magnetically coupled but electrically isolated.
They can step up or step down voltage levels depending on the number of turns in each coil.
Examples of transformers include power transformers used i...

- Q1. Max voltage of tansmission line in India?
- Ans.
The maximum voltage of transmission line in India is 765 kV.
The highest voltage level in India is 765 kV.
This voltage level is used for long distance transmission of electricity.
India has several high voltage transmission lines, including the Raigarh-Pugalur HVDC line.
The maximum voltage level has increased over the years, from 400 kV to 765 kV.
Higher voltage levels allow for more efficient transmission of electricity.
- Q2. Main protection for CT. Answer to this question is its secondary should be grounded
- Q3. Speed control methods for induction motors
- Ans.
Various methods like V/F control, rotor resistance control, and vector control are used for speed control of induction motors.
V/F control method varies the frequency and voltage supplied to the motor to control its speed.
Rotor resistance control method involves inserting external resistance in the rotor circuit to control the speed.
Vector control method uses advanced algorithms to control the speed and torque of the mo...

I applied via Whatsapp and was interviewed in May 2024. There were 2 interview rounds.
(2 Questions)
- Q1. What is the minimum megger value of good motor.
- Ans.
The minimum megger value of a good motor is typically 1 megohm or higher.
A good motor should have a megger value of at least 1 megohm to ensure proper insulation resistance.
Lower megger values may indicate insulation issues or potential breakdowns in the motor.
Regular megger testing is important to detect any insulation problems in motors.
For high voltage motors, the minimum megger value may be higher than 1 megohm.
- Q2. How much kva transformer is installed in my plant.
- Ans.
The kVA transformer installed in the plant is 500 kVA.
The kVA transformer installed in the plant is 500 kVA.
The kVA rating of the transformer is crucial for determining the power capacity of the plant.
It is important to regularly check and maintain the transformer to ensure optimal performance.
The kVA rating indicates the maximum load that the transformer can handle without overheating.
