NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q96-Q101):

NEW QUESTION # 96
What is the distance between points (3,5) and (4,5) on a rectangular coordinate grid?

Answer: D

Explanation:
The distance between two points with the same y-coordinate is the absolute difference in their x-coordinates.
|4 # 3| =1. NETA Level 2 technicians must demonstrate basic math skills for interpreting diagrams, test plots, and graphical data.


NEW QUESTION # 97
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 ÷ Secondary Voltage
= 13,200 ÷ 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 # 98
Which terminal set would you expect to find on adigital low-resistance ohmmeter (DLRO)?

Answer: B

Explanation:
DLROs use a four-wire (Kelvin) connection: two current terminals (C1, C2) and two potential terminals (P1, P2). This arrangement eliminates lead and contact resistance from measurements, ensuring accurate low- resistance readings for bolted joints, bus bars, and grounding connections.


NEW QUESTION # 99
According to NETA standards, what is themaximum allowable timetest instruments may remain in service before requiring recalibration?

Answer: D

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 # 100
For aDielectric Absorption Ratio (DAR)test on a transformer, the 1-minute insulation resistance value is divided by the value obtained at:

Answer: D

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 # 101
......
