The main reason why people look for NETA NETA_2 practice test is that these help them to prepare for the exam. Even if you study well but with no idea of the NETA Level 2 Certified Assistant Electrical Testing Specialist NETA_2 exam pattern, it will be tough to crack the nut. You shall waste your time thinking about the pattern and how to attempt the NETA Level 2 Certified Assistant Electrical Testing Specialist NETA_2 Exam Questions. On the other hand, if you know the NETA Level 2 Certified Assistant Electrical Testing Specialist NETA_2 exam questions well, you can use that time to solve the queries and improve your chances to score well in the exam.

NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q89-Q94):

NEW QUESTION # 89
Identify the substation bus arrangement that usestwo circuit breakers per circuit, allowing either breaker to be removed from service without interrupting load.

Answer: B

Explanation:
Adouble breaker busscheme assigns two breakers to each circuit, providing the highest level of reliability and operational flexibility. Either breaker can be removed for maintenance without interrupting service.
NETA Level 2 technicians must recognize bus schemes when performing commissioning tests, protection verification, and functional checks, as the scheme directly affects relay logic, interlocking, and testing sequences.


NEW QUESTION # 90
Transformer oil samples drawn when the oil temperature isbelow 32ยฐF (0ยฐC)may:

Answer: D

Explanation:
At low temperatures, free water can solidify and remain suspended, preventing accurate detection. NETA Level 2 technicians must consider temperature effects when interpreting oil analysis results.


NEW QUESTION # 91
When applying personal protective grounds, which connection must be madefirst?

Answer: A

Explanation:
The correct application of personal protective grounds is critical to worker safety and is strongly emphasized in NETA safety practices. When installing grounds, theequipment end must be attached first, ensuring the grounding conductor is securely bonded to earth or an effective ground source before any connection is made to energized or potentially energized conductors.
This sequence minimizes the risk of electric shock. If the phase conductor were connected first and the grounding system was not yet established, the worker could become the path to ground in the event of accidental energization. Once the equipment end is secured, phase conductors can be safely grounded.
When removing grounds, the reverse order is required: phase conductors are disconnected first, and the equipment end is removed last. NETA Level 2 technicians must follow this sequence consistently during maintenance, testing, and commissioning activities to ensure compliance with safety standards and prevent serious injury.


NEW QUESTION # 92
Class 00 rubber insulating gloves are proof-tested at2,500 VAC. What color label would you expect to find on these gloves?

Answer: A

Explanation:
Rubber insulating gloves are color-coded to indicate their voltage class and test rating.Class 00 gloves, rated for low-voltage work, are proof-tested at2,500 VACand are identified by awhite label.
NETA Level 2 technicians must verify glove class, test date, and physical condition before use. Using gloves of the incorrect class or expired test date creates a serious safety risk. Color identification allows quick visual verification in the field, supporting compliance with electrical safety requirements.


NEW QUESTION # 93
As frequency increases, theinductive reactanceof an inductor will:

Answer: A

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.
