I applied via Recruitment Consultant and was interviewed in Dec 2021. There was 1 interview round.

Interview Questionnaire 

10 Questions

  • Q1. Why transformer are rated in KVA.
  • Ans. 

    Transformers are rated in KVA because it represents the apparent power they can handle.

    • KVA stands for kilovolt-ampere, which is a unit of apparent power.

    • Transformers are designed to handle a certain amount of power, and the KVA rating indicates their capacity.

    • The KVA rating takes into account both the voltage and current that the transformer can handle.

    • It helps in determining the appropriate size and capacity of the tr...

  • Answered by AI
  • Q2. What is the ground clearance of 400KV transmission line.
  • Ans. 

    The ground clearance of a 400KV transmission line varies depending on various factors.

    • The ground clearance of a transmission line is the vertical distance between the lowest point of the conductor and the ground.

    • The ground clearance is determined based on safety regulations and requirements.

    • Factors that influence the ground clearance include terrain, vegetation, and proximity to buildings or roads.

    • In hilly areas, the g...

  • Answered by AI
  • Q3. What should be the tan Delta value of electrical equipment (for example T/F).
  • Ans. 

    The tan Delta value of electrical equipment should be as low as possible.

    • Tan Delta is a measure of the dielectric losses in electrical equipment.

    • A low tan Delta value indicates that the equipment has good insulation properties.

    • The tan Delta value can be affected by factors such as temperature, moisture, and aging of the equipment.

    • For transformers, a typical tan Delta value is around 0.001 or lower.

  • Answered by AI
  • Q4. Why ACSRinvar conductor are widely used in metro principal city.
  • Ans. 

    ACSRinvar conductors are widely used in metro principal cities due to their high strength and low thermal expansion.

    • ACSRinvar conductors have a high tensile strength, making them suitable for long-distance transmission lines in metro cities.

    • They have a low coefficient of thermal expansion, which helps in reducing sagging of the conductors and maintaining power transmission efficiency.

    • The use of ACSRinvar conductors in ...

  • Answered by AI
  • Q5. The Basis setting of REF protectionfor transformer should be how much.
  • Ans. 

    The Basis setting of REF protection for a transformer should be determined based on the transformer's characteristics and the system requirements.

    • The basis setting of REF (Restricted Earth Fault) protection for a transformer is typically determined by considering the transformer's winding configuration, impedance, and the system's fault level.

    • The setting should be chosen to ensure that the protection operates reliably ...

  • Answered by AI
  • Q6. The SF6 gas used for Ckt breaker chamber should be how much bar.
  • Ans. 

    The SF6 gas used for Ckt breaker chamber should be maintained at a pressure of around 5-7 bar.

    • The SF6 gas in the circuit breaker chamber should be maintained at a specific pressure to ensure proper functioning.

    • The recommended pressure for SF6 gas in the circuit breaker chamber is typically between 5 and 7 bar.

    • Maintaining the correct pressure helps in extinguishing the arc during circuit interruption.

    • Too low or too high...

  • Q7. Why star star zero phase shift transformer winding are used.
  • Ans. 

    Star-star zero phase shift transformer windings are used to provide a balanced three-phase output with zero phase shift between primary and secondary voltages.

    • Star-star zero phase shift transformer windings are commonly used in power distribution systems.

    • They are used to supply power to three-phase loads such as motors, generators, and transformers.

    • The windings are designed in such a way that the voltages in the primar...

  • Q8. What are the main difference between AIS and GIS Substation.
  • Ans. 

    AIS and GIS substations differ in their construction and insulation methods.

    • AIS (Air Insulated Substation) uses air as the insulation medium, while GIS (Gas Insulated Substation) uses SF6 gas.

    • AIS substations require larger land areas compared to GIS substations.

    • GIS substations are more compact and can be installed in urban areas where space is limited.

    • AIS substations are more susceptible to environmental factors like p...

  • Answered by AI
  • Q9. Why vibration damper are used with Conductor.
  • Ans. 

    Vibration dampers are used with conductors to reduce the risk of fatigue failure and damage caused by wind-induced vibrations.

    • Vibration dampers absorb and dissipate the energy generated by wind-induced vibrations in conductors.

    • They help to reduce the risk of fatigue failure and damage to the conductor and associated hardware.

    • Vibration dampers are typically installed at regular intervals along the length of the conducto...

  • Answered by AI
  • Q10. What is main function of LA in Substion.
  • Ans. 

    The main function of LA in a substation is to protect electrical equipment from lightning strikes.

    • LA stands for Lightning Arrester.

    • It is installed in substations to divert lightning strikes away from sensitive equipment.

    • LA provides a low-impedance path for lightning current to flow to the ground.

    • It helps in preventing damage to transformers, circuit breakers, and other electrical devices.

    • LA operates by ionizing the air...
