                            NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q50-Q55):

                            質問 # 50
                            Using a typical breaker control diagram, which coil is most commonly associated with theanti-pump function
                            ?

                            正解：C

                            解説：
                            Theanti-pump relay coilprevents repeated closing attempts if the close command remains energized after a breaker closes and trips. This protects mechanical components and ensures controlled operation. NETA Level
                            2 technicians must verify anti-pump operation during control circuit testing to ensure breakers cannot continuously reclose under fault conditions.


                            質問 # 51
                            Class 00 rubber insulating gloves are proof-tested at2,500 VAC. What color label would you expect to find on these gloves?

                            正解：D

                            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 # 52
                            Thebreaking capacityof a circuit breaker is typically expressed in:

                            正解：B

                            解説：
                            Breaking capacity refers to the maximumfault currenta circuit breaker can safely interrupt and is expressed in amperes(often kA). NETA Level 2 technicians must verify breaker ratings during acceptance testing to ensure suitability for the available short-circuit current at the installation location.


                            質問 # 53
                            Sample valves should be flushed with at least how much waste liquid before collecting a transformer oil sample?

                            正解：B

                            解説：
                            NETA-recommended oil sampling practices require flushing the sampling valve withat least one quartof waste liquid. This removes stagnant oil, debris, and contaminants that could skew test results.
                            Accurate oil analysis depends heavily on proper sampling technique. NETA Level 2 technicians must follow flushing and cleanliness requirements to ensure valid dielectric and moisture analysis.


                            質問 # 54
                            Duringprimary current injection testingof a low-voltage circuit breaker, the breaker trips instantaneously at
                            8× its long-time pickup setting, even though the instantaneous element is set to10×. What is the MOST likely cause?

                            正解：A

                            解説：
                            CT saturation occurs when the CT core cannot accurately reproduce high fault currents, causing distorted secondary current. This distortion can falsely trigger the instantaneous element at a lower current than expected. NETA Level 2 technicians must recognize CT saturation as a common cause of unexpected trip behavior during primary injection testing, particularly at high multiples of pickup.


                            質問 # 55
