LADWP ELECTRIC STATION OPERATOR
(CIRCUIT BREAKERS, DISCONNECTS,
TRANSFORMERS) EXAM | {LATEST 2026/ 2027
UPDATE} COMPLETE ACTUAL AND AUTHENTIC
EXAM | BRAND NEW!
LADWP Electric Station Operator (Circuit Breakers, Disconnects,
Transformers) Exam — Comprehensive exam preparation resource
designed for candidates preparing for the Los Angeles Department of
Water and Power (LADWP) Electric Station Operator assessment.
Covers essential electrical substation topics including circuit breaker
operation, disconnect switches, transformer fundamentals, protective
relays, switching procedures, safety regulations, electrical diagrams,
troubleshooting, and power distribution systems. Includes practice
questions and technical review material aimed at strengthening
operational knowledge, safety awareness, and exam readiness for
electric station operations roles. Field: Electrical Engineering.
Electrical __________ are installed in the path from the generator to
the consumer to provide reliability, flexibility, and safeguards for the
electrical power system.
Switches

A ___________-shaped coil allows a much stronger field to be created
than a flat coil does.
spiral
When current flow in a coil causes an emf to be induced in itself, it is
known as __________.
self induction
If a second coil is placed in the field of the first coil that is connected
to an AC source, the rising and collapsing magnetic field of the first
coil will cut across the second coil and will induce an AC voltage in the
second coil as well. This is known as __________ induction.
mutual
When there is no physical or electrical connection between the two
coils yet energy is transferred from one coil to the other. The coils are
said to be __________ coupled.
inductively

A simple power transformer essentially consists of two
windings
a measure of the ability of a substance to conduct magnetic lines of
force.
Permeability
__________ steel, which has a high permeability rating, is used as a
material for manufacturing transformer cores.
Silicon
Well-designed transformers are about _____% efficient.
98
Since they have no moving parts, the only losses are those caused by
field __________ when a transformer is energized, and resistance of
the core material.
