OVERHEAD NETWORKS
Reducing Outages with Automated Reclosing & Optimal Re-routing
Our Auto-Recloser detects transient & permanent faults on overhead distribution lines and automatically reroutes & restores the power supply. This helps reduce avoidable outages, improve feeder reliability, and minimise manual intervention.
How It Works?
Monitor
Current Sensor Tracks Line Current Continuously
Detect
Current Spikes Instantly When Fault Occurs
Trip
Circuit Opens to Interrupt Fault Current
Reclose
Automatic Attempt to Restore Service (1st, 2nd, 3rd cycle)
Clear
Permanent Fault Isolated, Transient Faults Cleared
Restore
Service Restored or Lockout Initiated
Solid Dielectric Auto-Recloser. It comes in 11KV & 33KV
