LADWP Electric Station Operator (Circuit Breakers, Disconnects, Transformers) exam questions and 100% Accurate answers 2026/2027 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. 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
