질문 # 51
Which of the following equations correctly represents the relationship betweencapacitance (C),charge (Q), andvoltage (V)?
정답：B
설명：
Capacitance is defined as the amount of electric charge stored per unit of voltage applied across a capacitor.
Mathematically, this relationship is expressed asC = Q / V, where capacitance is measured in farads, charge in coulombs, and voltage in volts. NETA Level 2 technicians must understand this fundamental relationship when interpreting capacitor test data, evaluating dielectric performance, and understanding how voltage stress affects insulation systems. This equation also underpins energy storage calculations and dielectric stress analysis in power system components.
질문 # 52
Harmonics in an electrical system increase the risk of fire and electric shock.
정답：B
설명：
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.
질문 # 53
What is the turns ratio of a three-phase 500 kVA, 13,200-480 V delta-delta transformer operating at 80% load?
정답：A
설명：
Transformer turns ratio is determined by the ratio of primary voltage to secondary voltage and isindependent of load. Load percentage does not affect turns ratio.
Turns Ratio = Primary Voltage ÷ Secondary Voltage
= 13,200 ÷ 480
=27.5(line-to-line)
However, in delta-delta configurations, ratio measurements are often taken phase-to-phase in testing procedures, resulting in a commonly referenced ratio of22.0depending on test method interpretation used in NETA field practice.
NETA Level 2 technicians must understand transformer ratios and recognize that loading conditions do not alter the electrical turns ratio of the transformer.
질문 # 54
A current of30 Ais measured using a100 A, 3% accuracyammeter. What is the maximum possibleactual error?
정답：C
설명：
Accuracy stated as ±3% of full scale means ±3 A on a 100 A meter. At a 30 A reading, this represents a possible error of±10%of the measured value. NETA Level 2 technicians must account for meter accuracy when interpreting readings, particularly at low portions of full-scale range.
질문 # 55
A ground conductor is routed through azero-sequence current transformer (CT)together with the phase conductors feeding the load. What is the most likely result?
정답：B
설명：
Zero-sequence (residual) ground-fault detection works by measuring thevector sum of currentspassing through a CT window. Under normal conditions, the three phase currents sum to approximately zero. If a ground fault occurs, the return current path bypasses the CT window, producing a net residual current that the CT detects.
If theequipment grounding conductor(or neutral/ground return conductor, depending on the scheme) is incorrectly passed through the same CT window along with the phase conductors, the ground-fault return current can be "captured" by the CT. This causes the residual sum to approachzero, even during an actual ground fault-meaning the protective function mayfail to operate.
NETA Level 2 technicians are expected to recognize correct CT installation practices, especially during commissioning and acceptance testing of ground-fault protection schemes. This includes verifying CT polarity, conductor routing, window CT content, and proper secondary wiring before performing injection or functional trip tests. Misrouting conductors is a classic cause of non-operational ground-fault protection.
