Interview Questionnaire
7 Questions
- Q1. Power factor improvement numerical
- Ans.
Power factor improvement involves reducing reactive power and increasing active power to improve efficiency.
Power factor is the ratio of active power to apparent power
Improving power factor reduces energy costs and improves system efficiency
Methods for improving power factor include capacitor banks, synchronous motors, and static VAR compensators
- Q2. Transformers EMF equation
- Q3. 3 pH induction motor slip ring and squeal cage motor difference
- Ans.
3-phase induction motor slip ring and squirrel cage motor differ in rotor construction and starting torque.
Slip ring motor has external resistors and brushes to control rotor current and torque, while squirrel cage motor has a simple rotor with copper bars.
Slip ring motor has high starting torque and is used in heavy load applications like cranes and elevators, while squirrel cage motor has low starting torque and is u...
- Q4. Shunt motor
- Q5. Cable layout
- Q6. Auto transformers
- Q7. Starting principal and speed control method of slip ring and squeal cage motor
- Ans.
Slip ring motors use external resistors for starting and speed control, while squirrel cage motors rely on the number of poles and frequency for speed control.
Slip ring motors have external resistors that are gradually removed to increase speed
Squirrel cage motors rely on the number of poles and frequency for speed control
Slip ring motors are used in applications where high starting torque is required
Squirrel cage moto...

- Q1. Taranformer rating ....... KVA MVA HZ
- Q2. Ohm low ...........
- Q3. Current of unit .......
- Ans.
The question is asking about the current of a unit.
The current of a unit refers to the amount of electric current flowing through a specific unit or device.
It is typically measured in amperes (A) or milliamperes (mA).
The current of a unit can vary depending on the specific device or circuit being discussed.
For example, the current of a unit could refer to the current flowing through a resistor, a transistor, or a motor...
- Q4. Transformers rating in KVA
- Ans.
Transformers are rated in KVA (kilovolt-amperes) to indicate their power capacity.
KVA stands for kilovolt-amperes, which is a unit of apparent power.
The KVA rating of a transformer indicates the maximum amount of power it can handle.
Transformers are available in various KVA ratings to suit different power requirements.
Higher KVA ratings indicate higher power capacity.
For example, a transformer with a 100 KVA rating can
- Q5. What is loop law?
- Ans.
Loop law, also known as Kirchhoff's voltage law, states that the sum of the voltages in any closed loop in a circuit is zero.
Loop law is a fundamental principle in electrical engineering.
It is also known as Kirchhoff's voltage law (KVL).
According to loop law, the algebraic sum of the potential differences (voltages) around any closed loop in a circuit is always zero.
It is based on the principle of conservation of energ...

- Q1. What is the Transformer
- Ans.
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 in power distribution, voltage regulation, and electrical isolation
