11KV Drop Out Surge Arrester Product Overview:
In the event of a diverter failure, the ground lead disconnector (GLD) operates to ensure network safety through a highly efficient sequential isolation process:
- Automatic Disconnection: The failed Drop Out Surge Arrester drops out, disconnecting itself automatically from the active network.
- Phase Isolation: Simultaneously, this action forces the fuse expulsion pole mounted 11kv carrier to drop out, effectively isolating the affected phase.
- Interlocking Safety: A built-in interlocking mechanism ensures that it is not possible to close the fuse carrier unless the arrester is safely in the closed position.
