Electrical Power Generation and Distribution

These flashcards cover key vocabulary and concepts related to electrical power generation and distribution systems.

Power Distribution

The process of taking electrical power from generation plants and delivering it to consumers.

High-voltage Transmission

The raising of voltage levels for the efficiency of power transmission, minimizing losses over distance.

Circuit Breaker

A protective device designed to interrupt the current flow when it detects abnormal conditions.

Surge Arrester

A device that protects electrical equipment from voltage spikes by redirecting the excess voltage to the ground.

Current Limiting Reactor

A device installed in series with a feeder to limit fault current while maintaining normal operations.

Disconnecting Switch

A switch that can only be operated when there is no current flowing, used for maintenance and rerouting power.

Tripping Action

The mechanism by which a circuit breaker opens to stop current flow in response to a fault condition.

Nameplate Information

Details provided on a durable plate attached to an electrical device, indicating operational characteristics.

Recloser

An automatic circuit breaker that attempts to reconnect after detecting a fault, adjusting based on fault conditions.

Sectionalizer

A device that isolates a faulty section of the circuit after monitoring the number of trips by a recloser.
