NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q25-Q30):

NEW QUESTION # 25
In which three-phase configuration areline current and phase current equal?

Answer: D

Explanation:
In awye (star)connection, line current equals phase current. In delta systems, line current is #3 times phase current. NETA Level 2 technicians must recognize this distinction when interpreting ammeter readings, evaluating load balance, and performing commissioning tests on three-phase systems.


NEW QUESTION # 26
As frequency increases, theinductive reactanceof an inductor will:

Answer: C

Explanation:
Inductive reactance is defined as. As frequency increases, inductive reactance increases proportionally. This principle is essential for understanding AC circuit behavior, harmonic effects, and frequency-dependent impedance during testing and troubleshooting.


NEW QUESTION # 27
Cells are connected inparallelin order to increase:

Answer: A

Explanation:
When cells are connected in parallel, the voltage of the battery bank remains the same as a single cell, but the current capacity (ampere-hours)increases. Parallel connections allow multiple cells to share load current, increasing the total available current without increasing voltage. NETA Level 2 technicians frequently encounter parallel battery strings in control power systems and must understand this relationship when evaluating capacity, load testing, and charger performance.


NEW QUESTION # 28
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 # 29
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: D

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 # 30
