NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q40-Q45):

NEW QUESTION # 40
Cells are connected inparallelin order to increase:

Answer: D

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 # 41
How many connection points are typically found on a Kelvin bridge used for low-resistance measurements?

Answer: D

Explanation:
A Kelvin bridge, also known as a four-wire resistance measurement device, usesfour connection pointsto accurately measure very low resistances. These consist of twocurrent terminalsand twopotential (voltage) terminals.
This configuration eliminates the effects of lead resistance and contact resistance, which can significantly distort measurements when testing bolted connections, bus joints, and grounding conductors. NETA Level 2 technicians routinely use Kelvin methods when performing low-resistance ohmic measurements during acceptance and maintenance testing.
Using fewer than four terminals would result in inaccurate readings, especially at milliohm or micro-ohm levels. Understanding this principle ensures proper test setup and reliable data interpretation.


NEW QUESTION # 42
What is the recommendedminimum insulation resistance valuefor motor windings manufactured before
1970?

Answer: B

Explanation:
For older motor windings, NETA guidance recognizes that insulation systems were often less robust than modern designs. The recommended minimum insulation resistance is100 megohms per kV of rated voltage plus 1 megohm.
This formula provides a baseline for evaluating insulation condition during acceptance or maintenance testing.
NETA Level 2 technicians must not only perform insulation resistance tests correctly, but also interpret results in the context of equipment age, voltage rating, and service conditions. Results below recommended minimums indicate potential moisture, contamination, or insulation degradation requiring corrective action.


NEW QUESTION # 43
Underground service conductors between the service equipment terminals and the service lateral are referred to as:

Answer: B

Explanation:
Service point conductors connect the utility service lateral to the service equipment terminals. Understanding conductor classification is important during inspection, testing, and verification of grounding and bonding systems. NETA Level 2 technicians must correctly identify conductor types to apply appropriate testing and safety requirements.


NEW QUESTION # 44
Which voltage is recommended by NETA-ATS for a15-minute AC withstand teston a three-phase34.5 kV line sectionalizerrated for a150 kV impulse withstand voltage?

Answer: C

Explanation:
NETA-ATS specifies withstand test voltages based on equipment rating and impulse withstand capability. For a 34.5 kV line sectionalizer with a 150 kV BIL, the recommended15-minute AC withstand test voltage is 78 kVAC. NETA Level 2 technicians must apply the correct test voltage to avoid damaging insulation while still verifying dielectric integrity.
