Interview Questionnaire 

9 Questions

  • Q1. Losses in Transformer
  • Ans. 

    Losses in transformers can be categorized as copper losses and iron losses.

    • Copper losses occur due to resistance in the windings and are also known as I^2R losses.

    • Iron losses occur due to hysteresis and eddy currents in the core.

    • Copper losses can be reduced by using larger conductors with lower resistance.

    • Iron losses can be minimized by using high-quality magnetic materials and proper core design.

    • Total losses in a tran...

  • Q2. Efficiency of a Transformer
  • Ans. 

    Efficiency of a transformer is the ratio of output power to input power.

    • Efficiency is affected by factors such as core losses, winding resistance, and load impedance.

    • Efficiency can be improved by using high-quality materials and reducing losses.

    • Efficiency is typically expressed as a percentage and can range from 50% to 99%.

    • Efficiency is important in reducing energy waste and improving overall system performance.

  • Answered by AI
  • Q3. How to reduce eddy current losses in transformer
  • Ans. 

    Eddy current losses in transformers can be reduced by using laminated cores, increasing the core resistance, and minimizing the air gap.

    • Use laminated cores to reduce eddy current losses

    • Increase the core resistance by using high resistivity materials

    • Minimize the air gap between the core and windings

    • Use magnetic materials with low hysteresis losses

    • Reduce the frequency of the alternating current

    • Use thicker laminations to ...

  • Answered by AI
  • Q4. Why high voltage is preferred for transmission of electrical power
  • Ans. 

    High voltage is preferred for transmission of electrical power due to lower energy losses and reduced cost.

    • High voltage reduces energy losses during transmission

    • Reduced current flow at high voltage reduces the cost of transmission lines

    • High voltage allows for longer transmission distances

    • Step-up transformers increase voltage for transmission and step-down transformers decrease voltage for distribution

    • Examples of high v...

  • Answered by AI
  • Q5. Why humming noise is generated during magnetostriction
  • Ans. 

    Humming noise is generated due to the vibration of magnetic domains in a magnetic material.

    • Magnetostriction is the property of magnetic materials to change their shape or dimensions when subjected to a magnetic field.

    • This change in shape causes the magnetic domains to vibrate, which in turn generates a humming noise.

    • The frequency of the humming noise is directly proportional to the frequency of the magnetic field.

    • Magne...

  • Answered by AI
  • Q6. Compare electrical circuit and magnetic circuit
  • Ans. 

    Electrical circuits involve the flow of electric current, while magnetic circuits involve the flow of magnetic flux.

    • Electrical circuits involve the use of conductors, insulators, and power sources to create a path for electric current to flow.

    • Magnetic circuits involve the use of magnetic materials, such as iron, to create a path for magnetic flux to flow.

    • Electrical circuits are used in a wide range of applications, inc...

  • Answered by AI
  • Q7. What is your dream or, what do you want to do in your life
  • Q8. Will you work with us if we give you posting far from your hometown
  • Q9. What are the electrical appliances
  • Ans. 

    Electrical appliances are devices that run on electricity to perform a specific task.

    • Examples include refrigerators, washing machines, televisions, air conditioners, and vacuum cleaners.

    • They are used in homes, offices, and industries for various purposes.

    • They make our lives easier and more convenient.

    • They require proper maintenance and care to ensure their longevity and safety.
