최신 NETA CAETS NETA_2 무료샘플문제 (Q64-Q69):

질문 # 64
On an electrical schematic, adot on a current transformer symbolindicates:

정답：A

설명：
The dot convention indicatespolarity, showing the instantaneous current direction relationship between primary and secondary windings. Correct polarity is critical for protection schemes, differential relays, and metering accuracy. NETA Level 2 technicians must verify CT polarity during installation and commissioning to ensure correct relay operation.


질문 # 65
Why shouldlint-free ragsbe used when cleaning circuit breaker components?

정답：D

설명：
Lint fibers can attract dust, moisture, and contaminants, which may degrade insulation and interfere with mechanical movement. NETA Level 2 technicians are expected to maintain cleanliness during maintenance and testing activities to prevent introducing foreign material that could affect breaker performance or reliability.


질문 # 66
What effect does enablingthermal memoryhave on thelong-time delay (LTD)operation of a low-voltage digital overcurrent protective device?

정답：D

설명：
Thermal memory accounts for residual heating in conductors and equipment following overloads. When enabled, itreduces the long-time delay operating time, allowing faster tripping if a subsequent overload occurs. NETA Level 2 technicians must understand this behavior during injection testing and when reviewing breaker trip performance.


질문 # 67
The sum of all voltage drops around aseries circuitis:

정답：B

설명：
Kirchhoff's Voltage Law states that the algebraic sum of voltages around any closed loop equals the applied voltage. This principle underpins circuit analysis and is essential for verifying expected readings during troubleshooting and commissioning.


질문 # 68
Class 00 rubber insulating gloves are proof-tested at2,500 VAC. What color label would you expect to find on these gloves?

정답：A

설명：
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.


질문 # 69
