A+ Graded
Question 1: One of the primary tasks of the Electric Station Operator is the
__________ of high-voltage circuits.
A) monitoring
B) switching
C) maintaining
D) designing
Correct Answer: B
Rationale: The primary operational task of the Electric Station Operator is switching
high-voltage circuits to control power flow, isolate equipment, and maintain system
reliability .
Question 2: The electrical function of switches falls into two categories; ___________
of relatively high values of current and voltage under load AND the switching of
circuits to provide a visual confirmation of de-energization.
A) manipulation
B) monitoring
,C) maintenance
D) measurement
Correct Answer: A
Rationale: The two functions are manipulation (switching under load) and providing
visual confirmation of de-energization .
Question 3: Electrical current may flow across the contacts of ____ to ____ electrical
switches before it reaches the consumer.
A) 10 to 20
B) 25 to 50
C) 50 to 100
D) 100 to 200
Correct Answer: C
Rationale: Electrical current may flow across the contacts of 50 to 100 electrical switches
before it reaches the consumer .
Question 4: __________ switching is for maintenance, construction, cleaning, testing,
etc.
A) Routine
B) Automatic
C) Emergency
D) Manual
Correct Answer: A
Rationale: Routine switching is planned work performed for maintenance, construction,
cleaning, and testing of equipment .
Question 5: __________ switching operations include automatic reclosers (ARs),
Voltage Pickup Units (VPUs), and Automatic Transfer Switching (ATSs).
,A) Manual
B) Emergency
C) Routine
D) Automatic
Correct Answer: D
Rationale: Automatic switching operations are performed by devices such as automatic
reclosers, VPUs, and ATSs without direct operator intervention .
Question 6: __________ switching is performed in response to power outages and
abnormal conditions such as overloads.
A) Routine
B) Automatic
C) Emergency
D) Scheduled
Correct Answer: C
Rationale: Emergency switching is performed by operators in response to power
outages and abnormal conditions such as overloads .
Question 7: Operators use electrical switches to perform routine, automatic, and
____________ switching operations on the electrical system.
A) scheduled
B) manual
C) emergency
D) maintenance
Correct Answer: C
Rationale: The three categories of switching operations are routine, automatic, and
emergency .
, Question 8: The placement of __________ electrical switches in the power system
makes it possible to limit both the duration and the extent of power outages.
A) manual
B) automatic
C) routine
D) emergency
Correct Answer: B
Rationale: Automatic switching devices respond instantly to system faults, limiting both
duration and extent of power outages .
Question 9: Bank switching is performed in substations: to provide adequate
capacity for customer load, to provide an alternate source for customer load when
equipment maintenance is required, and to:
A) reduce voltage
B) search for 4.8 kV grounds
C) increase frequency
D) balance phases
Correct Answer: B
Rationale: Bank switching is performed in substations for load management, alternate
source provision, and ground searches .
Question 10: __________ are electrical switches that are used to manipulate high
values of current and voltage in circuits that are carrying current or will be
carrying current following the operation.
A) Disconnects
B) Circuit breakers
C) Fuses
D) Relays
