NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q63-Q68):

質問 # 63
A battery bank consists of60 cells, each rated2 V. What is thenominal DC voltageof the battery bank?

正解：C

解説：
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.


質問 # 64
How many connection points are typically found on a Kelvin bridge used for low-resistance measurements?

正解：C

解説：
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.


質問 # 65
Which trigonometric function is equal to theopposite side divided by the hypotenuseof a right triangle?

正解：D

解説：
Thesineof an angle is defined as the ratio of the opposite side to the hypotenuse. Trigonometry is used in power factor analysis, phasor relationships, impedance calculations, and AC circuit analysis. NETA Level 2 technicians must understand these relationships when evaluating voltage, current, and phase angles in testing scenarios.


質問 # 66
Polarization Index (PI) is defined as the ratio of insulation resistance measured at:

正解：B

解説：
Polarization Index evaluates insulation quality over time and is calculated as:
PI = IR at 10 minutes ÷ IR at 1 minute.
NETA Level 2 technicians use PI testing to assess insulation dryness, cleanliness, and aging.


質問 # 67
What is the primary advantage ofaluminum bus barcompared to copper?

正解：D

解説：
Aluminum bus bar is widely used due to itslower costand lighter weight compared to copper. While copper has higher conductivity, aluminum provides an economical alternative when properly sized and installed.
NETA Level 2 technicians must recognize material properties when inspecting bus systems and evaluating resistance measurements.
