What potential hazard exist when switching from the ground using a telescopic
switch stick - ANSWER ✓ A person could still be exposed to an electric shock
with a high potential ground gradient is created around the base of a pool during a
switching operation
Why is it important to check that all three pools are open after opening a three
pole switch - ANSWER ✓ If not all are open the current in voltage on the whole
system will become on balance or could cause feral resistance
Why should I cut out and I'll be opened with a switch stick to interrupt load -
ANSWER ✓ A person can still be exposed to an electric shock with a high
potential ground gradient is created
Make a sectional Lizer be used by a line crew to interrupt load - ANSWER ✓ Yes
Why is it important to use a phasing tool before closing a switch between two
sources - ANSWER ✓ To make sure that the lines are in phase
Name four ways to verify line is isolated went applying a lock out tag out
procedure - ANSWER ✓ Visual opens, maps, dispatch, grounds
What potential hazard exist when operating in electronica recloser from the
control box mounted on the same structure - ANSWER ✓ The control box can
,become energized if the clothes are malfunctions or the bushings flap over the
control cable bonds together they were closer and control box
The control box can become energized if the clothes are malfunctions or the
bushings flap over the control cable bonds together they were closer and control
box - ANSWER ✓
What is the biggest advatage of AC power? - ANSWER ✓ 1. The easily
transformation from one voltage to another, Easy transformation allows the voltage
to be stepped up for efficient transmission of electrical energy over long distances.
Another advantage to AC power is that every time the voltage and current reverse
direction, the magnitude of the voltage and current is zero. This assists in
extinguishing arcs when opening switchgear.
What is monitored in a circuit to ensure that it stays constant right from the
generator to the customer? - ANSWER ✓ Frequency is measured. A typical range
for frequency is 59.97 Hz to 60.03 Hz Some systems are set up to start load
shredding when the frequency reaches 59.3 Hz
What changes occur to AC as it goes through a cycle? - ANSWER ✓ Rise and
fall of voltage and current
In relation to the peak value of AC power, what value do an ordinary ammeter and
voltmeter measure? - ANSWER ✓ The effective value of AC
What kind of AC load uses the energy needed to magnetize a motor or a
transformer winding? - ANSWER ✓ Inductive Load. An inductive load does not
generate heat or light
What kind of AC loads uses the energy needed to supply a capacitive effect at
capacitors, paralleling conductors, or in cables? - ANSWER ✓ Capacitive Load. A
Capacitive load does not generate heat or light.
What three types of load oppose the flow of current and form the total impedance
to a circuit? - ANSWER ✓ Resistive, Inductive, and Capacitive
Distribution feeders tend to have a combination of resistive load and inductive
load, creating a lagging power factor. What equipment is installed to counter a
lagging power factor? - ANSWER ✓ Capacitors
, What are the three types of power in an AC circuit - ANSWER ✓ Active,
Apparent, and Reactive Power
What are three applications of DC transmission lines? - ANSWER ✓ a. Long-
distance transmission of large amounts of power
b. Long lengths of underground or submarine cable
c. Tying together two AC systems with different frequencies
d. Tying together two different AC systems at locations where it is difficult to
maintain control of voltage, frequency, and power flow
e. A long length of distribution line to feed a small remote load, which would
otherwise need a high voltage transmission line and substation or its own
generation.
What advantage are there for a three-phase versus a single-phase circuit -
ANSWER ✓ Three phase allows for smoother power than the relatively, and more
pulsating power of a single phase (large generation, and larger motors)
What does it mean when the voltages of each phase of a three-phase circuit 120
degrees apart? - ANSWER ✓ Power generate in each coil reaches its peak and
direction at 120 degree apart
What can be done at a three-phase transformer bank if a customers three-phase
motor is running backward - ANSWER ✓ if it running backwards, switching any
two phases at the transformer will put the phase rotation back in sequence.
What determines whether a three-phase circuit is cosidered wye or delta? -
ANSWER ✓ wye has 4 wires with a neutral and delta has 3 wires with no neutral
What is the voltage-to-ground on a 4,160 V delta circuit - ANSWER ✓ you won't
get anything
Why does a source breaker see a phase-to-ground fault on a delta circuit? -
ANSWER ✓ becuase of a ground-fault relay picked up through the transformer
if the phase-to-phase voltage on a wye feeder is 25kV, what is the phase-to-ground
voltage? - ANSWER ✓ 14.45 kV
