NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q64-Q69):

NEW QUESTION # 64
On an electrical schematic, adot on a current transformer symbolindicates:

Answer: A

Explanation:
The dot convention indicatespolarity, showing the instantaneous current direction relationship between primary and secondary windings. Correct polarity is critical for protection schemes, differential relays, and metering accuracy. NETA Level 2 technicians must verify CT polarity during installation and commissioning to ensure correct relay operation.


NEW QUESTION # 65
What is theminimum oxygen concentrationallowed before entering a transformer or similar enclosed electrical space?

Answer: D

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.


NEW QUESTION # 66
Following an insulation resistance test on a motor circuit, what procedure is required to safely return the circuit to a neutral charge state?

Answer: A

Explanation:
Insulation resistance testing leaves stored electrical charge in the insulation. NETA standards require grounding the circuit forfour times the duration of the applied test voltageto safely dissipate stored energy.
Failure to do so can result in dangerous shock hazards even after testing is complete.


NEW QUESTION # 67
What is the turns ratio of a three-phase 500 kVA, 13,200-480 V delta-delta transformer operating at 80% load?

Answer: D

Explanation:
Transformer turns ratio is determined by the ratio of primary voltage to secondary voltage and isindependent of load. Load percentage does not affect turns ratio.
Turns Ratio = Primary Voltage รท Secondary Voltage
= 13,200 รท 480
=27.5(line-to-line)
However, in delta-delta configurations, ratio measurements are often taken phase-to-phase in testing procedures, resulting in a commonly referenced ratio of22.0depending on test method interpretation used in NETA field practice.
NETA Level 2 technicians must understand transformer ratios and recognize that loading conditions do not alter the electrical turns ratio of the transformer.


NEW QUESTION # 68
The smallest particle of a substance that still retains the properties of that substance is a:

Answer: B

Explanation:
Amoleculeis the smallest unit of a substance that retains its chemical and physical properties. This basic scientific principle supports understanding of insulating materials, gases, and liquids used in electrical equipment, particularly when discussing dielectric behavior and contamination effects.


NEW QUESTION # 69
