Bidoyng

Intermittent LV faults rupture fuses and disrupt supply. Bidoyng solves this with fast, automatic restoration and insights to support fault repair.

Product overview

Bidoyng is a high-performance single-shot auto-recloser that restores supply within the 3-minute outage window after intermittent LV faults occur, reducing customer interruptions. It alerts operators instantly on fuse rupture, calculates fault distance, and logs load profiles to support asset planning and network optimisation.

Key features

No interruptions

Allows fuse replacements without interrupting customer power.

Live load profiling

Captures real-time load data to support network analysis and planning.

Fault distance tool

Enables accurate fault location using distance-to-fault calculations.

High fault rating

Tested to 50 kA PSCC with a nominal load capacity of 400 A.

How does it work?

Bidoyng fits into existing LV fuse positions, with a primary fuse carrying load current in parallel with a secondary fuse and fault make switch.

When a fault causes the primary fuse to rupture, the secondary fuse is switched in after a user-programmed delay, allowing any moisture in the cable to disperse before re-energising the circuit to minimise customer interruption.

When an engineer attends site, the blown primary fuse can be replaced quickly and safely while maintaining supply to customers.
