NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q21-Q26):

NEW QUESTION # 21
For aDielectric Absorption Ratio (DAR)test on a transformer, the 1-minute insulation resistance value is divided by the value obtained at:

Answer: B

Explanation:
The Dielectric Absorption Ratio (DAR) is defined as:
DAR = IR at 60 seconds ÷ IR at 30 seconds
This test evaluates insulation quality by observing how resistance increases as polarization effects develop.
NETA Level 2 technicians use DAR testing as a quick diagnostic tool, particularly when full polarization index (PI) testing is not practical.


NEW QUESTION # 22
Which portion of a three-phase system carries current through the windings of a transformer or motor?

Answer: D

Explanation:
Phase currentis the current that flows through each individual winding of a three-phase device such as a transformer or motor. Understanding the difference between phase current and line current is critical because their magnitudes differ depending on whether the system is configured as wye or delta. NETA Level 2 technicians must correctly identify which current is being measured to avoid misinterpreting test results during commissioning, troubleshooting, and performance verification.


NEW QUESTION # 23
During avacuum circuit breaker bottle integrity test, which hazardous energy may be produced?

Answer: A

Explanation:
High-voltage vacuum integrity tests can generateX-raysdue to electron acceleration within the vacuum bottle.
NETA safety practices require distance, shielding, and time limitations during testing. Level 2 technicians must recognize non-obvious hazards associated with electrical testing, especially during high-voltage applications.


NEW QUESTION # 24
A 120 VAC, 60 Hz circuit supplies a 10 A load at a20° lagging power factor. What is thetrue power?

Answer: A

Explanation:
True power is calculated using.
Here,V,A, and.
Thus,W.
NETA Level 2 technicians must correctly distinguish apparent power from true power when evaluating loads, especially those with inductive characteristics.


NEW QUESTION # 25
What is themaximum allowable deviationbetween resistance measurements on bolted electrical connections?

Answer: C

Explanation:
NETA standards allow a maximum deviation of50%between comparable bolted connection resistance measurements. Deviations beyond this threshold may indicate loose hardware, corrosion, contamination, or improper installation. NETA Level 2 technicians must identify abnormal readings and recommend corrective action.
