NETA Level 2 Certified Assistant Electrical Testing Specialist NETA_2 Prüfungsfragen mit Lösungen (Q71-Q76):

71. Frage
Cells are connected inparallelin order to increase:

Antwort: C

Begründung:
When cells are connected in parallel, the voltage of the battery bank remains the same as a single cell, but the current capacity (ampere-hours)increases. Parallel connections allow multiple cells to share load current, increasing the total available current without increasing voltage. NETA Level 2 technicians frequently encounter parallel battery strings in control power systems and must understand this relationship when evaluating capacity, load testing, and charger performance.


72. Frage
Which ANSI device number corresponds to anundervoltage relay?

Antwort: D

Begründung:
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.


73. Frage
What is the distance between points (3,5) and (4,5) on a rectangular coordinate grid?

Antwort: D

Begründung:
The distance between two points with the same y-coordinate is the absolute difference in their x-coordinates.
|4 # 3| =1. NETA Level 2 technicians must demonstrate basic math skills for interpreting diagrams, test plots, and graphical data.


74. Frage
A ground conductor is routed through azero-sequence current transformer (CT)together with the phase conductors feeding the load. What is the most likely result?

Antwort: D

Begründung:
Zero-sequence (residual) ground-fault detection works by measuring thevector sum of currentspassing through a CT window. Under normal conditions, the three phase currents sum to approximately zero. If a ground fault occurs, the return current path bypasses the CT window, producing a net residual current that the CT detects.
If theequipment grounding conductor(or neutral/ground return conductor, depending on the scheme) is incorrectly passed through the same CT window along with the phase conductors, the ground-fault return current can be "captured" by the CT. This causes the residual sum to approachzero, even during an actual ground fault-meaning the protective function mayfail to operate.
NETA Level 2 technicians are expected to recognize correct CT installation practices, especially during commissioning and acceptance testing of ground-fault protection schemes. This includes verifying CT polarity, conductor routing, window CT content, and proper secondary wiring before performing injection or functional trip tests. Misrouting conductors is a classic cause of non-operational ground-fault protection.


75. Frage
During aCT saturation test, voltage increases sharply with little increase in current. What does this indicate?

Antwort: D

Begründung:
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.
