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 __________.
Circuit breakers - CORRECT ANSWER✔✔__________ are designed to open, close, energize, de-
energize, and interrupt normal and abnormal values of current flow in electrical circuits
Disconnects - CORRECT ANSWER✔✔__________ are provided as a method of visually
confirming that a circuit has been "disconnected" from specified sources of electrical energy.
Disconnects - CORRECT ANSWER✔✔__________ are used to energize or de-energize short
sections of conductor such as leads connecting a circuit breaker to its associated disconnects.
