NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q14-Q19):

NEW QUESTION # 14
Which document should be consultedfirstbefore performing any circuit breaker testing or maintenance?

Answer: D

Explanation:
NETA standards require technicians to followmanufacturer's instructionsfirst, as they define specific procedures, tolerances, and limitations for the equipment. NETA standards supplement-not replace- manufacturer requirements.


NEW QUESTION # 15
A battery bank consists of60 cells, each rated2 V. What is thenominal DC voltageof the battery bank?

Answer: B

Explanation:
Battery bank voltage is calculated by summing the individual cell voltages in series:
60 × 2 V =120 V
NETA Level 2 technicians routinely test station batteries used for control power and protection systems.
Accurate voltage verification is critical for ensuring breaker tripping capability and relay operation during loss of AC power.


NEW QUESTION # 16
Shown below is a current transformer with multiple secondary taps. What is the calculated voltage between tapsX1 and X3when200 Vis applied across the full secondary windingX1 to X5?

Answer: D

Explanation:
The voltage developed across a portion of a CT secondary winding is proportional to the number of turns between the selected taps. If 200 V is applied across the full winding from X1 to X5, and the diagram shows that taps X1 to X3 represent 30% of the total turns, then the voltage across X1-X3 is:
200 V × 0.30 =60 V
NETA Level 2 technicians must understand tap relationships during saturation testing, ratio testing, and troubleshooting CT secondary circuits. Incorrect assumptions about tap voltages can result in inaccurate test results or insulation damage during testing.


NEW QUESTION # 17
What is the distance between points (3,5) and (4,5) on a rectangular coordinate grid?

Answer: A

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 # 18
You arrive to perform acceptance testing on a newly installed indoor 15 kV switchgear lineup. Covers are removed and conductors are exposed with taped ends. What is thecorrect initial action?

Answer: A

Explanation:
Before any testing or inspection begins, NETA safety practices require verification of anelectrically safe work condition. Even newly installed equipment may be energized unintentionally or improperly isolated.
Exposed conductors increase the risk of shock and arc flash.
The correct action is tovisually confirm that all sources of power have been de-energized, followed by properlockout/tagoutprocedures. This ensures no unexpected energization can occur during testing activities.
NETA Level 2 technicians must never assume equipment is safe based on installation status. Safety verification always precedes inspection, testing, or commissioning work.


NEW QUESTION # 19
......

As long as you enter the learning interface of our soft test engine of NETA_2 quiz guide and start practicing on our Windows software, you will find that there are many small buttons that are designed to better assist you in your learning.
