Description
Substations are crucial components of electrical power systems, responsible for transforming voltage levels, switching circuits, and protecting equipment. They act as transfer points in the electrical grid, connecting generation, transmission, and distribution networks. Key features include transformers, switch gear, and control systems, all working together to ensure efficient and safe energy delivery.
Switching and Control:Includes circuit breakers, dis-connectors, and other devices for switching circuits on and off.
- Control systems:
Monitor and manage the substation’s operation, including protection relays, metering equipment, and communication interfaces.
- Busbars:
Conductors that interconnect various electrical equipment within the substation.
- Protection:
- Circuit breakers:Automatically interrupt electrical circuits in case of faults (overloads, short circuits).
- Protective relays:Monitor voltage and current, sending trip signals to circuit breakers when faults are detected.
- Lightning arresters: Protect equipment from voltage surges caused by lightning strikes.
