27kV auto recloser​ Vacuum Recloser with Control

⚡ Boost Grid Reliability with 27kV Pole-Mounted Auto Recloser

The 27kV Auto Vacuum Recloser is a smart pole-mounted switching device engineered for automatic fault isolation and self-reclosing in medium-voltage distribution networks. Ideal for 27kV overhead lines, this recloser minimizes service interruptions caused by temporary faults, such as lightning or tree contact.

Manufactured under IEC 62271-111 / IEEE C37.60, the recloser integrates vacuum interrupters, a high-speed control unit, and wireless communication options for SCADA systems. It’s widely used in rural electrification, smart grids, and renewable energy systems.

❓ FAQ – 27kV Auto Vacuum Recloser

• How many times can it reclose after a fault?
Typically set to 3 or 4 times, programmable through the control panel.

• Can it detect permanent vs. transient faults?
Yes. Smart controller differentiates fault types and locks out on persistent failures.

• Is communication encrypted?
Supported protocols use industry-standard security layers.

• Is the device maintenance-free?
Designed for minimal intervention. Yearly inspection is sufficient in most settings.

• Does it support GPS time-sync?
Yes, GPS-based time synchronization is optional for event tracking accuracy.
