최신 NETA CAETS NETA_2 무료샘플문제 (Q68-Q73):

질문 # 68
For photovoltaic (PV) systems, which device converts direct-current (DC) input into alternating-current (AC) output?

정답：C

설명：
Photovoltaic systems generatedirect current (DC)electricity as a result of solar energy interacting with semiconductor materials. However, most building electrical systems and utility grids operate onalternating current (AC). The device responsible for converting DC output from PV arrays into usable AC power is an inverter.
Inverters perform more than simple conversion. Modern PV inverters also regulate voltage, synchronize frequency and phase with the utility grid, provide ground-fault detection, and include anti-islanding protection. NETA Level 2 technicians are expected to understand inverter operation because acceptance and maintenance testing often includes verifying correct inverter output voltage, frequency, and protective functions.
A rectifier performs the opposite function, converting AC to DC, and is commonly found in battery chargers and DC power supplies. Transformers change voltage levels but do not convert DC to AC.Converters may change DC voltage levels but do not produce alternating current.
Understanding inverter functionality is essential when testing renewable energy systems, performing commissioning activities, and verifying compliance with applicable electrical and safety standards.


질문 # 69
What is themaximum allowable deviationbetween resistance measurements on bolted electrical connections?

정답：D

설명：
NETA standards allow a maximum deviation of50%between comparable bolted connection resistance measurements. Deviations beyond this threshold may indicate loose hardware, corrosion, contamination, or improper installation. NETA Level 2 technicians must identify abnormal readings and recommend corrective action.


질문 # 70
In azone-interlocked low-voltage circuit breakerscheme, if the breaker responsible for clearing a fault fails to operate, which statement is correct?

정답：A

설명：
Zone-selective interlocking (ZSI) improves coordination by allowing downstream devices to trip first while restraining upstream devices. If the downstream breaker fails to clear the fault, restraint signals are removed and thenext upstream breaker tripsto isolate the fault.
NETA Level 2 technicians must understand this fail-safe behavior when commissioning protection systems and validating coordination logic.


질문 # 71
When applying personal protective grounds, which connection must be madefirst?

정답：C

설명：
The correct application of personal protective grounds is critical to worker safety and is strongly emphasized in NETA safety practices. When installing grounds, theequipment end must be attached first, ensuring the grounding conductor is securely bonded to earth or an effective ground source before any connection is made to energized or potentially energized conductors.
This sequence minimizes the risk of electric shock. If the phase conductor were connected first and the grounding system was not yet established, the worker could become the path to ground in the event of accidental energization. Once the equipment end is secured, phase conductors can be safely grounded.
When removing grounds, the reverse order is required: phase conductors are disconnected first, and the equipment end is removed last. NETA Level 2 technicians must follow this sequence consistently during maintenance, testing, and commissioning activities to ensure compliance with safety standards and prevent serious injury.


질문 # 72
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：A

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.
