Substations depends on the battery systems to keep essential functions well especially when AC power fails.
These batteries provide a reliable DC supply that ensures safety, protection and control at all times.
Reasons for Substations to use Batteries
Uninterrupted Protection
Protection relays, trip circuits and breakers must operate instantly during faults.
Batteries guarantee tripping power even during total AC outages.
Reliable Control & Automation
SCADA , control relays, annunciators and communication equipment depend on stable DC power to monitor and control the grid.
Safe Circuit Breaker Operation
DC batteries energize trip and close coils ensuring breakers can open to clear faults (or) close when commanded without delay.
Blackout Readiness
During blackouts batteries keep the substation operational and observable enabling safe restoration of power.
Noise-Free, Stable Power
Battery DC is clean and steady which is ideal for sensitive electronics compared to AC supplies.
Typical Battery Systems
110 V / 220 V DC battery banks.
Lead-acid (or) VRLA batteries with redundant chargers.
Designed for hours of autonomy based on load and standards.
