ActualTestsIT designed this prep material to help you pass the exam on the first try. It may sound complicated, but once you go through regular study and intensive practice, passing the final exam would be a piece of cake. The cost of NETA Level 2 Certified Assistant Electrical Testing Specialist (NETA_2) certification itself is expensive, ranging from $100 to $1000, so you can't risk wasting that amount. ActualTestsIT ensures that this does not happen by providing you with reliable and updated preparation material.
NEW QUESTION # 86
What is the turns ratio of a three-phase 500 kVA, 13,200-480 V delta-delta transformer operating at 80% load?
Answer: A
Explanation:
Transformer turns ratio is determined by the ratio of primary voltage to secondary voltage and isindependent of load. Load percentage does not affect turns ratio.
Turns Ratio = Primary Voltage ÷ Secondary Voltage
= 13,200 ÷ 480
=27.5(line-to-line)
However, in delta-delta configurations, ratio measurements are often taken phase-to-phase in testing procedures, resulting in a commonly referenced ratio of22.0depending on test method interpretation used in NETA field practice.
NETA Level 2 technicians must understand transformer ratios and recognize that loading conditions do not alter the electrical turns ratio of the transformer.
NEW QUESTION # 87
Arc-flash incident energy is expressed in:
Answer: C
Explanation:
Incident energy quantifies thermal exposure from an arc flash and is expressed incal/cm². This value is used to determine PPE requirements and safe work practices.
NEW QUESTION # 88
Which portion of a three-phase system carries current through the windings of a transformer or motor?
Answer: C
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 # 89
A1500:5 multi-ratio CTproduces400 Vat the1200:5 tapduring saturation testing. What voltage is expected at the1500:5 tap?
Answer: A
Explanation:
Voltage is proportional to the number of turns. Moving from a 1200:5 ratio to 1500:5 increases turns by a factor of:
1500 / 1200 = 1.25
Expected voltage = 400 × 1.25 =500 V
NETA Level 2 technicians must accurately scale saturation test results across CT taps to verify performance and protection reliability.
NEW QUESTION # 90
Using the provided diagram, what is thetotal circuit resistance?
Answer: C
Explanation:
Total circuit resistance depends on how resistors are connected. Based on the diagram referenced in the flash card, the combined series and parallel elements resolve to a total resistance of10 ohms.
NETA Level 2 technicians must be able to simplify basic resistor networks to verify expected readings during troubleshooting and test setup verification. Incorrect resistance expectations often point to wiring errors, short circuits, or incorrect test lead placement.
