NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q35-Q40):

質問 # 35
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?

正解：B

解説：
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.


質問 # 36
During avacuum circuit breaker bottle integrity test, which hazardous energy may be produced?

正解：D

解説：
High-voltage vacuum integrity tests can generateX-raysdue to electron acceleration within the vacuum bottle.
NETA safety practices require distance, shielding, and time limitations during testing. Level 2 technicians must recognize non-obvious hazards associated with electrical testing, especially during high-voltage applications.


質問 # 37
Polarization Index (PI) is defined as the ratio of insulation resistance measured at:

正解：A

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 # 38
Class 00 rubber insulating gloves are proof-tested at2,500 VAC. What color label would you expect to find on these gloves?

正解：B

解説：
Rubber insulating gloves are color-coded to indicate their voltage class and test rating.Class 00 gloves, rated for low-voltage work, are proof-tested at2,500 VACand are identified by awhite label.
NETA Level 2 technicians must verify glove class, test date, and physical condition before use. Using gloves of the incorrect class or expired test date creates a serious safety risk. Color identification allows quick visual verification in the field, supporting compliance with electrical safety requirements.


質問 # 39
Cells are connected inseriesin order to increase:

正解：D

解説：
When electrical cells are connected in series, their individual voltages add together, increasing the overall voltage ratingof the battery string. Current capacity remains the same as that of a single cell.
NETA Level 2 technicians frequently encounter battery banks used for control power, protective relays, and emergency systems. Understanding series versus parallel connections is essential when testing battery voltage, interpreting readings, and diagnosing capacity or voltage issues during commissioning and maintenance.
