All these three NETA NETA_2 exam questions formats contain the real and updated NETA_2 exam questions. These NETA Level 2 Certified Assistant Electrical Testing Specialist (NETA_2) exam questions are being presented in practice test software and PDF dumps file formats. The NETA_2 desktop practice test software is easy to use and install on your desktop computers. Whereas the other NETA NETA_2 web-based practice test software is concerned, this is a simple browser-based application that works with all operating systems. Both practice tests are customizable, simulate actual exam scenarios, and help you overcome mistakes.

NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q66-Q71):

NEW QUESTION # 66
During charging of lead-acid batteries, whichexplosive gasmay be generated?

Answer: D

Explanation:
Hydrogen gas is produced during battery charging due to electrolysis of water in the electrolyte. Hydrogen is highly explosive at relatively low concentrations. NETA Level 2 technicians must ensure adequate ventilation, eliminate ignition sources, and follow battery safety procedures during testing and maintenance.


NEW QUESTION # 67
In which three-phase configuration areline current and phase current equal?

Answer: B

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 # 68
In apurely inductive circuit, what is the phase relationship between voltage and current?

Answer: B

Explanation:
In a purely inductive circuit, current lags voltage by90 degrees, meaning voltage leads current by 90°. This phase relationship is foundational to understanding AC circuit behavior, protective relay operation, and power factor calculations-all within the expected knowledge scope of a NETA Level 2 technician.


NEW QUESTION # 69
Which portion of an electrical transmission system experiences faultsmost frequently?

Answer: D

Explanation:
Overhead transmission lines experience the highest frequency of faults due to their direct exposure to environmental conditions. Wind, lightning, ice, vegetation contact, animals, and pollution all contribute to transient and permanent fault conditions on overhead conductors. Unlike underground systems, overhead lines are not shielded from weather-related events.
NETA Level 2 technicians must understand fault likelihood when interpreting protective relay operations, breaker trips, and event records. Many relay schemes are designed with reclosing logic specifically because overhead line faults are often temporary. This understanding supports proper commissioning, testing of protective devices, and evaluation of fault-clearing performance.


NEW QUESTION # 70
Each switchboard used asservice equipmentmust be provided with amain bonding jumper.

Answer: D

Explanation:
A main bonding jumper is required to connect the grounded conductor (neutral) to the equipment grounding conductor at the service disconnect. This establishes a low-impedance fault return path necessary for overcurrent devices to operate promptly. NETA Level 2 technicians must verify proper bonding during acceptance and maintenance inspections because improper bonding can lead to elevated touch potentials and ineffective fault clearing.


NEW QUESTION # 71
