LADWP ELECTRIC STATION
OPERATOR UPDATED ACTUAL Test
Questions And Correct Answers
switching - CORRECT ANSWERS One of the primary tasks of the Electric Station Operator is the
__________ of high voltage circuits.
50 100 - CORRECT ANSWERS Electrical current may flow across the contacts of ____ to ____
electrical switches before it reaches the consumer.
improper - CORRECT ANSWERS 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 ANSWERS 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 ANSWERS Operators use electrical switches to perform routine,
automatic, and ____________ switching operations on the electrical system.
Routine - CORRECT ANSWERS ___________ switching is for maintenance, construction,
cleaning, testing, etc.
Automatic - CORRECT ANSWERS ___________ switching operations include automatic
reclosers (ARs), Voltage Pickup Unit (VPUs), and Automatic Transfer Switching (ATSs).
Emergency - CORRECT ANSWERS ___________ switching operations include insolate trouble,
restoration, 4.8kV Ground Search, etc.
Automatic - CORRECT ANSWERS 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 ANSWERS __________ switching performed by Operators in usually in
response to power outages and abnormal conditions such as overloads.
manipulation - CORRECT ANSWERS 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 ANSWERS __________ 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 ANSWERS Transformers and voltage regulators must be energized
and de-energized using __________.
Circuit breakers - CORRECT ANSWERS __________ are designed to open, close, energize, de-
energize, and interrupt normal and abnormal values of current flow in electrical circuits
Disconnects - CORRECT ANSWERS __________ are provided as a method of visually confirming
that a circuit has been "disconnected" from specified sources of electrical energy.
Disconnects - CORRECT ANSWERS __________ are used to energize or de-energize short
sections of conductor such as leads connecting a circuit breaker to its associated disconnects.
Disconnects - CORRECT ANSWERS __________ are not designed to interrupts current flow, open
or close circuits, or energize and de-energize circuits other than short sections.
10 20 - CORRECT ANSWERS During abnormal conditions, current often exceeds the normal
limitation of these devices by as much as _____ to _____ times their normal rating.
