最新的 NETA CAETS NETA_2 免費考試真題 (Q88-Q93):

問題 #88
In azone-selective interlocking (ZSI)scheme, what condition allows an upstream breaker to tripwithout intentional delay?

答案：D

解題說明：
In ZSI schemes, downstream breakers send restraint signals upstream when they detect faults. Ifno restraint signal is received, the upstream breaker assumes the downstream device failed and tripswithout intentional delayto clear the fault. NETA Level 2 technicians must understand this fail-safe logic when commissioning protection systems and verifying selective coordination.


問題 #89
The dataplate on a condenser bushing listsC2values. What do these values represent?

答案：B

解題說明：
C2 values represent the capacitance and power factor measured between the test tap and ground flange. These values are critical for evaluating bushing condition and detecting contamination, moisture ingress, or insulation deterioration during acceptance and maintenance testing.


問題 #90
Harmonics in an electrical system increase the risk of fire and electric shock.

答案：A

解題說明：
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.


問題 #91
Which section of a switchboard receives power from theservice sectionand distributes it to downstream loads?

答案：A

解題說明：
The distribution section of a switchboard receives incoming power from the service section and feeds branch circuits, feeders, or downstream panels. During commissioning, NETA Level 2 technicians verify continuity, torque, insulation, and protective coordination within the distribution section to ensure reliable power delivery and safe operation.


問題 #92
To reverse the direction of rotation of a three-phase induction motor, which action is required?

答案：B

解題說明：
The direction of rotation of a three-phase motor is determined by thephase sequenceof the supply voltage.
Reversingany two phase conductorschanges the phase sequence, which reverses the rotating magnetic field in the stator and therefore reverses motor rotation.
NETA Level 2 technicians frequently verify motor rotation during commissioning and after maintenance.
Understanding phase rotation is essential when performing bump tests, troubleshooting incorrect rotation, or verifying wiring after motor replacement. Reversing all three phases would preserve the original phase sequence and would not change rotation.
