AEP Inspection & Quality Control 3 — Questions and Answers
Question 1: What is the minimum information that must be included on a construction material's inspection tag or sticker to confirm it passed quality inspection?
- Only the inspector's name
- Inspector ID or signature, date of inspection, and acceptance status (Correct answer)
- The purchase order number and delivery date
- The manufacturer's serial number only
Correct answer: Inspector ID or signature, date of inspection, and acceptance status
An inspection tag must include the inspector's identification, the date, and a clear pass/fail or acceptance status to provide a traceable quality record.
Question 2: When torqueing bolts on a high-voltage disconnect switch, a technician should verify torque values against which document?
- The crew foreman's verbal instruction
- The manufacturer's installation manual or AEP engineering specifications (Correct answer)
- The OSHA general industry standard only
- The previous year's maintenance log
Correct answer: The manufacturer's installation manual or AEP engineering specifications
Manufacturer installation manuals and engineering specifications provide the authoritative torque values for high-voltage equipment to ensure proper mechanical and electrical connections.
Question 3: A quality audit of a construction project finds that required daily inspection reports were not completed for three consecutive days. This is best classified as:
- A minor observation requiring no formal action
- A documentation non-conformance requiring corrective action (Correct answer)
- An acceptable practice if the work was visually satisfactory
- A matter to be addressed only at project closeout
Correct answer: A documentation non-conformance requiring corrective action
Missing required inspection documentation is a non-conformance against the project's quality plan and requires formal corrective action to restore compliance.
Question 4: Which condition on a fiberglass hot stick would require it to be immediately removed from service?
- A faded color on the grip handle
- Surface tracking, cracks, or moisture contamination on the insulated section (Correct answer)
- Minor scuffs on the tool attachment end
- A label that is partially peeled off
Correct answer: Surface tracking, cracks, or moisture contamination on the insulated section
Surface tracking, cracks, or moisture on a hot stick's insulated section compromises its dielectric properties and creates a lethal shock hazard for the user.
Question 5: What standard process is used to verify that a newly installed protection relay operates correctly before energizing a circuit?
- A load flow calculation
- Secondary injection testing using a relay test set (Correct answer)
- A visual inspection of the relay panel wiring only
- Confirming the relay model number matches the design drawing
Correct answer: Secondary injection testing using a relay test set
Secondary injection testing applies simulated fault currents to relay inputs to verify that the relay operates at the correct settings and within acceptable timing tolerances.
Question 6: When reviewing weld quality on a steel transmission tower, which type of defect is most difficult to detect with the naked eye but is detectable via ultrasonic testing (UT)?
- Surface porosity
- Underfill at the weld crown
- Subsurface cracks or lack of fusion (Correct answer)
- Excessive weld spatter
Correct answer: Subsurface cracks or lack of fusion
Subsurface cracks and lack-of-fusion defects are internal to the weld and cannot be seen visually, making ultrasonic testing the appropriate non-destructive examination method.
Question 7: An AEP inspector is reviewing a contractor's material certifications (mill certs) for structural steel. What is the inspector primarily verifying?
- That the steel was purchased from a US supplier
- That the material's chemical composition and mechanical properties meet the specified standard (Correct answer)
- That the steel was delivered on schedule
- That the material was painted before delivery
Correct answer: That the material's chemical composition and mechanical properties meet the specified standard
Mill certifications document the actual chemical and mechanical test results for a batch of steel, which the inspector compares against the project specification to confirm compliance.
