최신 NETA CAETS NETA_2 무료샘플문제 (Q19-Q24):

질문 # 19
A control contact that includes one normally open (NO) contact and one normally closed (NC) contact operated by a single actuator is classified as which contact form?

정답：D

설명：
Control contacts are categorized by their functional behavior and internal configuration. AForm C contact consists ofone normally open (NO) and one normally closed (NC) contactthat share a common movable contact and operate together. When the actuator changes state, one contact opens while the other closes.
This configuration is commonly used in control circuits where a change of state must simultaneously initiate one function and terminate another, such as interlocking schemes, status indication, and control logic. NETA Level 2 technicians frequently encounter Form C contacts in relays, auxiliary switches on circuit breakers, and motor control equipment.
Form A contacts are normally open only, while Form B contacts are normally closed only. Form C provides greater flexibility and is widely used in protection and control systems. Correct identification of contact forms is critical during continuity testing, functional verification, and troubleshooting of control circuits.


질문 # 20
What is the recommendedminimum insulation resistance valuefor motor windings manufactured before
1970?

정답：A

설명：
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.


질문 # 21
What is meant by adead-tank circuit breaker?

정답：D

설명：
Adead-tank circuit breakeris designed so that the interrupter assembly and associated operating components are contained within ametal tank that is bonded to ground potential. Because the enclosure is grounded ("dead"), the tank is not energized during normal operation. This construction reduces touch potential hazards and provides a robust, grounded barrier around interrupting components.
This contrasts with alive-tank breaker, where the external housing or tank is atline potential, requiring greater external clearances and insulation coordination. From a testing perspective, NETA Level 2 work commonly includes verifying breaker integrity through insulation resistance, contact resistance, functional checks, and in some applications, power factor testing or vacuum bottle integrity testing (depending on breaker type). Understanding "dead-tank" vs "live-tank" is important because it influences safe work practices, test lead placement, and interpretation of results (particularly for insulation-related tests and grounding considerations).
NETA objectives emphasize technicians being able to identify equipment construction types and apply the appropriate test approach and safety controls, especially regarding grounded enclosures, bonding, and the management of induced or stored energy.


질문 # 22
OSHA requires testing of a voltmeterafterverifying absence of voltage when testing circuits above what voltage level?

정답：B

설명：
A core safety practice in electrical testing is verifying that your voltage tester is functioning properlyboth before and afterperforming a test for absence of voltage. This practice is commonly summarized as"live- dead-live": test the meter on a known live source, test the circuit (dead check), then re-test on a known live source to ensure the meter didn't fail during the process.
Within OSHA-related electrical safety expectations and common field practice aligned with NETA work, this verification is emphasized especially in higher-voltage contexts, and the flash-card target here isabove 600 V.
Above this threshold, the consequences of a false "dead" reading are severe, and verification of instrument operation becomes non-negotiable.
NETA Level 2 technicians must demonstrate disciplined instrument verification habits. Even if a meter reads zero, it must be proven functional immediately afterward. This prevents relying on a meter with a blown fuse, dead battery, damaged leads, or internal failure-each of which could incorrectly indicate "no voltage" on an energized system.


질문 # 23
During aCT saturation test, voltage increases sharply with little increase in current. What does this indicate?

정답：C

설명：
A sharp rise in voltage with minimal increase in current indicates the CT core has reachedmagnetic saturation. Beyond this point, the CT cannot accurately reproduce primary current. NETA Level 2 technicians must identify saturation points to ensure CTs are suitable for protection applications and that relay performance will be reliable during high-current faults.
