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

  • Answered by AI
  • 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

(2 Questions)

  • Q1. What is Transformer
  • Ans. 

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

    • Transformers are used to increase or decrease the voltage in an electrical circuit.

    • They consist of two or more coils of wire, known as windings, that are wound around a core made of magnetic material.

    • The primary winding receives electrical energy from a power source, while the secondary ...

  • Q2. What is rectifier
  • Ans. 

    A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

    • Rectifiers are commonly used in power supplies to convert AC voltage to DC voltage.

    • They are made up of diodes, which allow current to flow in only one direction.

    • Rectifiers can be half-wave or full-wave, depending on the number of diodes used.

    • Examples of rectifiers include bridge rectifiers, vacuum tube rectifiers, and soli

Round 1 - Technical 

(5 Questions)

  • 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...
