NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q85-Q90):

質問 # 85
Underground service conductors between the service equipment terminals and the service lateral are referred to as:

正解：C

解説：
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.


質問 # 86
An induction motor has a 40 kVA input, a power factor of 0.82, and an efficiency of 92%. What is the approximate output horsepower?

正解：C

解説：
To calculate motor horsepower, real power must first be determined. Real power (kW) is calculated by multiplying apparent power (kVA) by power factor:
Real Power = 40 kVA × 0.82 = 32.8 kW
Next, efficiency must be applied to determine output power:
Output Power = 32.8 kW × 0.92 = 30.176 kW
Horsepower is calculated by converting kilowatts to horsepower using the conversion factor:
1 HP # 0.746 kW
Horsepower = 30.176 ÷ 0.746 #30.2 HP
NETA Level 2 technicians are expected to understand power relationships, including apparent power, real power, power factor, and efficiency. These calculations are commonly used when evaluating motor performance, loading conditions, and acceptance testing results.


質問 # 87
ASTM D 924 is a required acceptance test for liquid-filled transformers containing natural ester insulating fluid according to NETA standards.

正解：D

解説：
ASTM D 924 defines test methods forpower factor and dielectric lossof insulating liquids. NETA standards require this test for acceptance testing of liquid-filled transformers, including those usingnatural ester insulating fluids.
Power factor testing evaluates the condition of the insulating liquid by identifying contamination, moisture, and deterioration. Natural ester fluids, while environmentally advantageous, still require dielectric evaluation to ensure reliability and safety.
NETA Level 2 technicians must be familiar with required acceptance tests and understand why dielectric properties are critical indicators of insulation health.


質問 # 88
As frequency increases, theinductive reactanceof an inductor will:

正解：C

解説：
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.


質問 # 89
Harmonics in an electrical system increase the risk of fire and electric shock.

正解：C

解説：
Harmonics cause increased heating in conductors, transformers, and neutral paths, which can degrade insulation and increase fire risk. They can also create unexpected voltage conditions and elevated touch potentials. NETA Level 2 technicians must recognize harmonic-related risks when evaluating system performance, especially in facilities with nonlinear loads such as VFDs and power electronics.
