LADWP Electric Station Operator (Circuit
Breakers, Disconnects, Transformers) Exam
Questions and Answers 2026/2027
switching - correct answer-One of the primary tasks of the Electric Station
Operator is the __________ of high voltage circuits.
50 100 - correct answer-Electrical current may flow across the contacts of ____ to
____ electrical switches before it reaches the consumer.
improper - correct answer-The __________ operation of these electrical switches
can pose a serious hazard to personnel, can cause destruction of expensive power
system equipment, and can cause unnecessary interruption of electrical service to
consumers.
switches - correct answer-Electrical __________ are installed in the path from the
generator to the consumer to provide reliability, flexibility, and safeguards for the
electrical power system.
emergency - correct answer-Operators use electrical switches to perform routine,
automatic, and ____________ switching operations on the electrical system.
, Routine - correct answer-___________ switching is for maintenance,
construction, cleaning, testing, etc.
Automatic - correct answer-___________ switching operations include automatic
reclosers (ARs), Voltage Pickup Unit (VPUs), and Automatic Transfer Switching
(ATSs).
Emergency - correct answer-___________ switching operations include insolate
trouble, restoration, 4.8kV Ground Search, etc.
Automatic - correct answer-The placement of ___________ electrical switches in
the power system makes it possible to limit both the duration and the extent of
power outages.
Emergency - correct answer-__________ switching performed by Operators in
usually in response to power outages and abnormal conditions such as overloads.
manipulation - correct answer-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.
Circuit breakers - correct answer-__________ 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.
Circuit breakers - correct answer-Transformers and voltage regulators must be
energized and de-energized using __________.
