🔸 An electrical substation is responsible for transforming, distributing, and protecting electrical power within the grid. The operational process includes:
⭕ Power Reception & Voltage Transformation:
✅ Receives high-voltage electricity from transmission lines.
✅ Step-down transformers reduce voltage for distribution.
⭕ Switching & Protection:
✅ Circuit breakers isolate faults automatically.
✅ Disconnect switches enable manual isolation for maintenance.
✅ Relays & surge arresters protect equipment from faults and surges.
⭕ Power Distribution:
✅ Busbars distribute power among feeders.
✅ Feeders & capacitor banks supply electricity efficiently.
⭕ Monitoring & Control:
✅ SCADA systems enable remote operation.
✅ Meters & sensors track voltage, current, and power flow.
⭕ Maintenance & Safety:
✅ Routine inspections prevent failures.
✅ Emergency protocols ensure grid stability.
✅ Strict safety standards protect personnel and equipment.
⭕ Conclusion:
🔸 An electrical substation plays a crucial role in power transformation, switching, protection, and distribution. Its efficient operation ensures a stable and safe supply of electricity to consumers.
