LADWP Electric Station Operator (Circuit Breakers,
Disconnects, Transformers) Exam 2026/2027 Questions And
Correct Answers Graded A+
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.
Circuit breakers
__________ 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
Transformers and voltage regulators must be energized and de-energized using
__________.
Circuit breakers
__________ are designed to open, close, energize, de-energize, and interrupt
normal and abnormal values of current flow in electrical circuits
Disconnects
__________ are provided as a method of visually confirming that a circuit has
been "disconnected" from specified sources of electrical energy.
Disconnects
, __________ are used to energize or de-energize short sections of conductor such
as leads connecting a circuit breaker to its associated disconnects.
Disconnects
__________ are not designed to interrupts current flow, open or close circuits, or
energize and de-energize circuits other than short sections.
10 20
During abnormal conditions, current often exceeds the normal limitation of these
devices by as much as _____ to _____ times their normal rating.
Dielectric medium
This is the insulating mechanism that occupies the space between the open contacts
of a CB and prevents the flow of current through the device while the contacts are
in the open position.
Dielectric
The ability of a substance to prevent the flow of electrical current is described as
its __________ strength.
Conductors
__________ of electricity have no dielectric strength, as they allow current to flow
in a circuit.
