                            NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q37-Q42):

                            NEW QUESTION # 37
                            Polarization Index (PI) is defined as the ratio of insulation resistance measured at:

                            Answer: D

                            Explanation:
                            Polarization Index evaluates insulation quality over time and is calculated as:
                            PI = IR at 10 minutes ÷ IR at 1 minute.
                            NETA Level 2 technicians use PI testing to assess insulation dryness, cleanliness, and aging.


                            NEW QUESTION # 38
                            On an electrical schematic, adot on a current transformer symbolindicates:

                            Answer: D

                            Explanation:
                            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.


                            NEW QUESTION # 39
                            Which terminal set would you expect to find on adigital low-resistance ohmmeter (DLRO)?

                            Answer: C

                            Explanation:
                            DLROs use a four-wire (Kelvin) connection: two current terminals (C1, C2) and two potential terminals (P1, P2). This arrangement eliminates lead and contact resistance from measurements, ensuring accurate low- resistance readings for bolted joints, bus bars, and grounding connections.


                            NEW QUESTION # 40
                            According to NETA standards, what is themaximum allowable timetest instruments may remain in service before requiring recalibration?

                            Answer: B

                            Explanation:
                            NETA standards require test instruments to be calibrated at leastonce every 12 monthsto ensure measurement accuracy and traceability. Using out-of-calibration instruments can invalidate test results and compromise safety decisions. NETA Level 2 technicians must verify calibration labels, dates, and traceability before using any test equipment in the field.


                            NEW QUESTION # 41
                            Which portion of a three-phase system carries current through the windings of a transformer or motor?

                            Answer: D

                            Explanation:
                            Phase currentis the current that flows through each individual winding of a three-phase device such as a transformer or motor. Understanding the difference between phase current and line current is critical because their magnitudes differ depending on whether the system is configured as wye or delta. NETA Level 2 technicians must correctly identify which current is being measured to avoid misinterpreting test results during commissioning, troubleshooting, and performance verification.


                            NEW QUESTION # 42
                            ......
