Q: Which of the following is a primary objective of substation maintenance?

Ensuring the reliable and safe operation of equipment. — Reliability and safety are the most important objectives.

Q: What is the primary function of a circuit breaker in a substation?

To protect equipment and personnel by interrupting fault currents. — Circuit breakers protect against overcurrents and short circuits.

Q: Which maintenance activity is typically performed on power transformers?

Oil testing and analysis. — Oil testing helps to detect internal problems.

Q: What is the purpose of insulation resistance testing (meggering)?

To assess the condition of insulation. — Meggering checks the insulation's ability to resist current flow.

Q: Which of the following should be included in a good substation maintenance schedule?

Regular inspections, testing, and preventative maintenance. — Proactive maintenance is key for reliability.

Q: What safety precautions must be followed during substation maintenance?

Lockout/Tagout procedures, use of PPE, and adherence to safety protocols. — Safety is paramount; Lockout/Tagout, PPE, and protocols are essential.

Q: What is the primary purpose of a lightning arrester?

To protect equipment from voltage surges caused by lightning. — Lightning arresters protect against transient overvoltages.

Q: Which of the following is a common visual inspection performed in a substation?

Checking for signs of overheating, corrosion, and leaks. — Visual inspections are a first step to identify potential problems.

Q: What type of maintenance is often performed on protective relays?

Calibration and functional testing. — Relays need to be calibrated to function properly.

Q: What should be done when a piece of equipment is found to be defective during maintenance?

Remove it from service and repair or replace it immediately. — Defective equipment needs prompt attention to avoid failures.
