NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q91-Q96):

質問 # 91
Identify the substation bus arrangement that usestwo circuit breakers per circuit, allowing either breaker to be removed from service without interrupting load.

正解：B

解説：
Adouble breaker busscheme assigns two breakers to each circuit, providing the highest level of reliability and operational flexibility. Either breaker can be removed for maintenance without interrupting service.
NETA Level 2 technicians must recognize bus schemes when performing commissioning tests, protection verification, and functional checks, as the scheme directly affects relay logic, interlocking, and testing sequences.


質問 # 92
Which type of load is most commonly associated withharmonic distortion?

正解：B

解説：
Variable frequency drives (VFDs) are nonlinear loads that draw current in pulses, producing harmonics.
Understanding harmonic sources helps technicians evaluate heating, nuisance tripping, and power quality issues.


質問 # 93
What is the recommendedminimum insulation resistance valuefor motor windings manufactured before
1970?

正解：B

解説：
For older motor windings, NETA guidance recognizes that insulation systems were often less robust than modern designs. The recommended minimum insulation resistance is100 megohms per kV of rated voltage plus 1 megohm.
This formula provides a baseline for evaluating insulation condition during acceptance or maintenance testing.
NETA Level 2 technicians must not only perform insulation resistance tests correctly, but also interpret results in the context of equipment age, voltage rating, and service conditions. Results below recommended minimums indicate potential moisture, contamination, or insulation degradation requiring corrective action.


質問 # 94
During avacuum circuit breaker bottle integrity test, which hazardous energy may be produced?

正解：B

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 # 95
Which ANSI device number corresponds to anundervoltage relay?

正解：C

解説：
ANSI device27designates anundervoltage relay. This relay operates when system voltage falls below a preset threshold and is commonly used for motor protection, load shedding, and system interlocking. NETA Level 2 technicians must recognize ANSI device numbers to correctly identify protective functions during testing, troubleshooting, and commissioning.
