AND SOLUTIONS GRADED A+
⩥ Inverter. Answer: A device that changes direct-current input to an
alternating-current output.
⩥ Form C. Answer: A type of contact that is identified by NC and NO
separated by a node.
⩥ Personal protective grounds attachment order. Answer: The equipment
end is attached first.
⩥ Horsepower of an induction motor. Answer: 30.2 HP, given 40kVA
input power, a power factor of 82 percent, and an efficiency of 92
percent.
⩥ Connection points on a kelvin bridge. Answer: 4 connection points.
⩥ Acceptance testing procedure for new-indoor 15KV switch lineup.
Answer: Visually confirm that the source of power has already been de-
energized and lock out.
,⩥ Turns ratio of a transformer. Answer: 22.000 for a 3-phase 500kVA,
13,200-480 volt rated delta-delta transformer that is 80% loaded.
⩥ ASTM D 924. Answer: A required acceptance test for liquid-filled
transformers with natural ester insulating fluid per NETA standards.
⩥ Test decal color for minor deficiency. Answer: Yellow test decal
affixed to equipment after electrical tests.
⩥ Dead tank breaker. Answer: The external tank is grounded.
⩥ Ground fault protection with zero-sequence CT. Answer: Ground fault
protection won't function if the ground conductor runs through the zero-
sequence CT with current carrying conductors.
⩥ 52 device. Answer: Best described as an AC circuit breaker.
⩥ Total power dissipation of a series circuit. Answer: 25 W, given two
resistors dissipating 10 W and 15 W.
⩥ Best choice for circuit breakers and switches. Answer: Mobil 28 for
use in both the conductive and mechanical areas.
, ⩥ Power factor temperature correction value for new mineral oil.
Answer: 20C/40C.
⩥ OSHA voltage test requirement. Answer: Testing of a volt meter is
required after a voltage test on voltage above 600V.
⩥ Tagout device strength. Answer: A tagout device must be strong
enough to remain attached under a minimum of 50 lbs of force.
⩥ Mil-foot. Answer: A piece of wire that is 0.001 inches in diameter and
12 inches long is one mil-foot.
⩥ Electrical equipment access. Answer: At least 2 entrances of sufficient
area must be provided giving access to the electrical equipment working
space.
⩥ Restricted Approach Boundary for 69kV. Answer: The Restricted
Approach Boundary for a 69kV system is 3 ft 10 in.
⩥ Fault occurrence in transmission. Answer: The portion of the
transmission system where faults occur most frequently is overhead
lines.
⩥ Reversing motor direction. Answer: To reverse the direction of
rotation of a three-phase motor, reverse any two leads.
