CAST Test Planning and Management 2 — Questions and Answers
Question 1: When planning a transformer protection test, why is a clear scope of work defined before starting?
- To set boundaries, required tests, and acceptance criteria (Correct answer)
- To increase billable hours
- To skip safety reviews
- To avoid documenting results
Correct answer: To set boundaries, required tests, and acceptance criteria
A defined scope establishes what will be tested, the methods, and the pass/fail criteria.
Question 2: A test plan should identify required tools and instruments primarily to:
- Ensure correct, calibrated equipment is available on site (Correct answer)
- Impress the client
- Reduce the number of technicians
- Eliminate the need for procedures
Correct answer: Ensure correct, calibrated equipment is available on site
Listing instruments ensures the right calibrated tools are ready, preventing delays and inaccurate readings.
Question 3: Which factor most affects scheduling of an outage-based electrical test?
- Coordination with operations to de-energize equipment (Correct answer)
- The technician's lunch break
- Paint color of the panel
- Brand of multimeter
Correct answer: Coordination with operations to de-energize equipment
Outage tests require coordinating with operations to safely de-energize equipment within an approved window.
Question 4: What is the main purpose of a job hazard analysis in test planning?
- Identify and control risks before work begins (Correct answer)
- Calculate project profit
- Assign parking spaces
- Order replacement parts
Correct answer: Identify and control risks before work begins
A JHA identifies hazards and the controls needed before the task starts.
Question 5: Why are baseline measurements valuable in a maintenance test program?
- They provide a reference to detect future degradation (Correct answer)
- They replace manufacturer data
- They eliminate retesting
- They lower equipment cost
Correct answer: They provide a reference to detect future degradation
Baselines give a known starting point so trends and deterioration can be tracked over time.
Question 6: A test procedure document should include all EXCEPT:
- The technician's personal phone number (Correct answer)
- Step-by-step instructions
- Safety precautions
- Acceptance limits
Correct answer: The technician's personal phone number
Procedures cover steps, safety, and limits—not personal contact details.
Question 7: Before energizing equipment after testing, the team should first:
- Remove grounds and verify the system is restored to normal (Correct answer)
- Leave all jumpers in place
- Disconnect the meter only
- Skip the checklist
Correct answer: Remove grounds and verify the system is restored to normal
All temporary grounds and test connections must be removed and the system restored before re-energizing.
