NEW QUESTION # 46
Which ANSI device number corresponds to anundervoltage relay?
Answer: A
Explanation:
ANSI device27designates anundervoltage relay. This relay operates when system voltage falls below a preset threshold and is commonly used for motor protection, load shedding, and system interlocking. NETA Level 2 technicians must recognize ANSI device numbers to correctly identify protective functions during testing, troubleshooting, and commissioning.
NEW QUESTION # 47
Which trigonometric function is equal to theopposite side divided by the hypotenuseof a right triangle?
Answer: D
Explanation:
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.
NEW QUESTION # 48
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?
Answer: A
Explanation:
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.
NEW QUESTION # 49
Cells are connected inparallelin order to increase:
Answer: C
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 # 50
A transformer contains insulating fluid with aspecific gravity greater than 1. From where should the oil sample be drawn?
Answer: A
Explanation:
Specific gravity greater than 1 means the insulating fluid isheavier than water. Any free water contamination will settlebelowthe oil. To avoid collecting settled contaminants and to obtain a representative oil sample, NETA practice requires sampling from thetop of the tank.
Correct sampling technique is critical for accurate dielectric, moisture, and dissolved gas analysis results.
NETA Level 2 technicians must understand fluid properties to avoid misleading test conclusions.
