Top 10 Questions for Sub Master Interview

1. How would you troubleshoot an issue where a substation is experiencing voltage fluctuations?

To troubleshoot this issue, I would begin by checking the following:

• The condition of the substation’s transformers and other equipment.
• The load on the substation.
• The condition of the substation’s grounding system.
• The condition of the substation’s protection system.

2. What are the different types of protection systems used in substations?

Overcurrent protection

• Current transformers (CTs) are used to sense the current flowing through the substation equipment.
• The CTs are connected to overcurrent relays, which trip the circuit breakers if the current exceeds a predetermined value.

Overvoltage protection

• Voltage transformers (VTs) are used to sense the voltage on the substation equipment.
• The VTs are connected to overvoltage relays, which trip the circuit breakers if the voltage exceeds a predetermined value.

Ground fault protection

• Ground fault relays are used to detect ground faults on the substation equipment.
• The ground fault relays trip the circuit breakers if a ground fault is detected.

3. What are the different types of substation maintenance?

The different types of substation maintenance include:

• Preventive maintenance: This type of maintenance is performed on a regular basis to prevent problems from occurring.
• Corrective maintenance: This type of maintenance is performed to repair problems that have already occurred.
• Emergency maintenance: This type of maintenance is performed to address problems that pose an immediate danger to the substation or its personnel.

4. What are the different types of substation equipment?

The different types of substation equipment include:

• Transformers: Transformers are used to change the voltage of the electricity that flows through the substation.
• Circuit breakers: Circuit breakers are used to protect the substation equipment from damage in the event of a fault.
• Switches: Switches are used to connect and disconnect the substation equipment.
• Relays: Relays are used to protect the substation equipment from damage in the event of a fault.

5. What are the different types of substation layouts?

The different types of substation layouts include:

• Single-line diagram: This type of layout shows the one-line diagram of the substation.
• Two-line diagram: This type of layout shows the two-line diagram of the substation.
• Three-line diagram: This type of layout shows the three-line diagram of the substation.

6. What are the different types of substation construction?

The different types of substation construction include:

• Overhead construction: This type of construction is used for substations that are located outdoors.
• Underground construction: This type of construction is used for substations that are located underground.
• Indoor construction: This type of construction is used for substations that are located indoors.

7. What are the different types of substation testing?

The different types of substation testing include:

• Electrical testing: This type of testing is used to verify the electrical integrity of the substation equipment.
• Mechanical testing: This type of testing is used to verify the mechanical integrity of the substation equipment.
• Thermal testing: This type of testing is used to verify the thermal integrity of the substation equipment.

8. What are the different types of substation safety?

The different types of substation safety include:

• Electrical safety: This type of safety is used to protect the substation personnel from electrical hazards.
• Mechanical safety: This type of safety is used to protect the substation personnel from mechanical hazards.
• Fire safety: This type of safety is used to protect the substation from fires.

9. What are the different types of substation maintenance?

The different types of substation maintenance include:

• Preventive maintenance: This type of maintenance is used to prevent problems from occurring.
• Corrective maintenance: This type of maintenance is used to repair problems that have already occurred.
• Emergency maintenance: This type of maintenance is used to address problems that pose an immediate danger to the substation or its personnel.

10. What are the different types of substation equipment?

The different types of substation equipment include:
