NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q49-Q54):

NEW QUESTION # 49
According to NETA standards, what is themaximum allowable timetest instruments may remain in service before requiring recalibration?

Answer: A

Explanation:
NETA standards require test instruments to be calibrated at leastonce every 12 monthsto ensure measurement accuracy and traceability. Using out-of-calibration instruments can invalidate test results and compromise safety decisions. NETA Level 2 technicians must verify calibration labels, dates, and traceability before using any test equipment in the field.


NEW QUESTION # 50
Which type of load is most commonly associated withharmonic distortion?

Answer: A

Explanation:
Variable frequency drives (VFDs) are nonlinear loads that draw current in pulses, producing harmonics.
Understanding harmonic sources helps technicians evaluate heating, nuisance tripping, and power quality issues.


NEW QUESTION # 51
ASTM D 924 is a required acceptance test for liquid-filled transformers containing natural ester insulating fluid according to NETA standards.

Answer: C

Explanation:
ASTM D 924 defines test methods forpower factor and dielectric lossof insulating liquids. NETA standards require this test for acceptance testing of liquid-filled transformers, including those usingnatural ester insulating fluids.
Power factor testing evaluates the condition of the insulating liquid by identifying contamination, moisture, and deterioration. Natural ester fluids, while environmentally advantageous, still require dielectric evaluation to ensure reliability and safety.
NETA Level 2 technicians must be familiar with required acceptance tests and understand why dielectric properties are critical indicators of insulation health.


NEW QUESTION # 52
What is theprimary purposeof the National Electrical Code (NEC)?

Answer: B

Explanation:
The NEC exists to providepractical safeguardsagainst electrical hazards that can cause injury, fire, or property damage. It is not a design manual, testing standard, or training guide, but a safety code intended to minimize risk through installation requirements.
NETA Level 2 technicians must understand that testing and commissioning activities support the NEC's safety intent. Verifying grounding, bonding, overcurrent protection, clearances, and labeling helps ensure installations meet the NEC's fundamental objective of protecting people and property from electrical hazards.


NEW QUESTION # 53
What is theminimum oxygen concentrationallowed before entering a transformer or similar enclosed electrical space?

Answer: A

Explanation:
An oxygen concentration of11.5%represents a dangerous condition that can rapidly impair physical and cognitive function. NETA safety guidance requires oxygen levels to be verified before entry into confined or enclosed spaces such as transformers. Entry below safe oxygen thresholds requires specialized respiratory protection and controls.
