switching One of the primary tasks of the Electric Station
Operator is the __________ of high voltage circuits.
50 100 Electrical current may flow across the contacts of ____
to ____ electrical switches before it reaches the
consumer.
, improper 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 Electrical __________ are installed in the path from the
generator to the consumer to provide reliability,
flexibility, and safeguards for the electrical power
system.
emergency Operators use electrical switches to perform routine,
automatic, and ____________ switching operations on the
electrical system.
Routine ___________ switching is for maintenance, construction,
cleaning, testing, etc.
Automatic ___________ switching operations include automatic
reclosers (ARs), Voltage Pickup Unit (VPUs), and
Automatic Transfer Switching (ATSs).
Emergency ___________ switching operations include insolate
trouble, restoration, 4.8kV Ground Search, etc.
Automatic The placement of ___________ electrical switches in the
power system makes it possible to limit both the
duration and the extent of power outages.
Emergency __________ switching performed by Operators in usually
in response to power outages and abnormal
conditions such as overloads.
manipulation 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.
