Basic QA/QC Electrical

Q:-1. What is the role of an Electrical QA/QC Engineer?

Ans:-To ensure all electrical installations meet project specifications, quality standards, and safety regulations.

Q:-2. What is an Inspection and Test Plan (ITP)?

Ans:-A document outlining inspection and testing requirements for electrical work.

Q:-3. What is a Site Inspection Request (SIR)?

Ans:-A request submitted for the inspection of completed electrical work before approval.

Q:-4. What is a Non-Conformity Report (NCR)?

Ans:-A report issued when electrical work does not meet project specifications or standards.

Q:-5. What is an Electrical Method of Statement (MOS)?

Ans:-A document detailing step-by-step procedures for electrical installations.

Q:-6. What is a Single Line Diagram (SLD)?

Ans:-A simplified representation of an electrical power distribution system.

Q:-7. What is an Insulation Resistance (Megger) Test?

Ans:-A test measuring insulation quality between conductors to prevent leakage currents.

Q:-8. What is a High-Potential (Hi-Pot) Test?

Ans:-A test applying high voltage to cables to check for insulation breakdown.

Q:-9. What is an Earth Resistance Test?

Ans:-A test measuring the resistance of grounding systems for electrical safety.

Q:-10. What is a Phase Rotation Test?

Ans:-A test ensuring the correct sequence of phases in a three-phase system.

Q:-11. What is a Circuit Breaker Contact Resistance Test?

Ans:-A test measuring resistance across breaker contacts to ensure efficiency.

Q:-12. What is the purpose of a Transformer?

Ans:-To step up or step down voltage levels for efficient power distribution.

Q:-13. Why is proper cable sizing important?

Ans:-To prevent overheating, voltage drop, and electrical failures.

Q:-14. What is an Earthing System?

Ans:-A system that connects electrical equipment to the ground to prevent shocks and faults.

Q:-15. What is a Protection Relay?

Ans:-A device that detects faults and triggers protective actions in an electrical system.

Q:-16. What is the purpose of a Residual Current Device (RCD)?

Ans:-To protect against electric shock by detecting leakage currents.

Q:-17. Why is Lockout-Tagout (LOTO) important?

Ans:-It ensures electrical systems are properly shut off before maintenance, preventing accidental energization.

Q:-18. What is an Arc Flash Hazard?

Ans:-A dangerous electrical explosion caused by high fault currents.
