LADWP ELECTRIC STATION OPERATOR (CIRCUIT
BREAKERS, DISCONNECTS, TRANSFORMERS) QUESTIONS
WITH 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.
