QUESTION 1
When a lineman is required to work on a de-energized overhead
transmission line, which of the following steps must be taken first to
ensure the safety of the crew?
A) Place a ground on all three phases at the work site.
B) Verify that the line is de-energized using a properly rated proximity
indicator.
C) Apply hold-off tags and personal danger tags at all points of possible
re-energization.
D) Request a switching order from the system operator.
Answer: D
Explanation: The correct procedure begins with obtaining a switching
order from the system operator. This formal request ensures that all
necessary clearances and switching arrangements are initiated by the
,2|Page
authority having jurisdiction. Placing grounds, verifying de-energization,
and applying tags are all subsequent steps that occur after the
switching order is received. The switching order provides a legally and
operationally binding framework for the outage.
QUESTION 2
The minimum approach distance for a lineman working on energized
equipment with a nominal voltage of 230 kV is most accurately
determined by which of the following factors?
A) The type of rubber gloves being used and their class rating.
B) The phase-to-phase voltage and the transient overvoltage study for
that line.
C) The utility's historical data on line outages in that specific area.
D) The ambient temperature and relative humidity on the day of the
work.
Answer: B
Explanation: Minimum approach distances are established based on the
phase-to-phase voltage and the anticipated transient overvoltage.
OSHA and IEEE standards require that the transient overvoltage be
calculated for the specific system to determine the electrical component
of the safe distance. While glove classes and environmental factors
influence overall safety, they are not the primary determinants for
establishing the initial distance.
QUESTION 3

Which of the following best describes the function of a static wire
(overhead ground wire) on a transmission line?
A) To provide a low-impedance path for lightning currents and shield
the phase conductors.
B) To serve as a neutral conductor for the return of unbalanced load
current.
C) To support fiber-optic communication cables for system monitoring.
D) To balance the inductive reactance between the three phases.
Answer: A
Explanation: The static wire, typically located at the top of the
transmission structure, is designed to intercept lightning strikes and
conduct the resulting current to ground through the tower footing
resistance. Its primary purpose is shielding the phase conductors from
direct lightning strikes. The other options describe neutral conductors,
OPGW (optical ground wire) use, or transposition, but do not define the
core protective function.
QUESTION 4
In the context of distribution systems, what is the primary purpose of a
recloser?
A) To disconnect the line permanently when a fault is detected.
B) To automatically interrupt and reclose the circuit several times to
clear temporary faults.
C) To regulate voltage levels on long distribution feeders.
, 4|Page
D) To isolate a faulty transformer without de-energizing the entire
feeder.
Answer: B
Explanation: A recloser is an intelligent overcurrent protection device
that senses faults and automatically opens to interrupt current. It is
programmed to reclose after a brief delay to determine if the fault,
typically a temporary one such as a lightning strike or a tree branch, has
cleared. If the fault persists after a preset number of operations, the
recloser locks open. This functionality improves service continuity.
QUESTION 5
When setting a pole in rocky terrain, which of the following is the most
appropriate method to ensure structural stability?
A) Use a power auger to drill a hole in the rock and plant the pole
directly.
B) Dig a shallow hole and use a concrete pad at the surface only.
C) Blast a hole using explosives and backfill with native soil.
D) Install the pole in a drilled hole and use crushed stone and rock
anchors or a stub guy.
Answer: D
Explanation: In rocky terrain where excavation for traditional pole depth
is not feasible, rock anchors or stubbing a pole into a drilled socket with
crushed stone provides the necessary lateral and vertical support. A
