Safety Brief - Pig Tail Crush in Fuse Canister of EFACEC Switchgear

Background

A recent incident occurred while Essential Energy workers where in the process of commissioning a new Tyree Pad Mounted Substation.

After the High Voltage (HV) EFACEC switchgear was energised, field workers were at the Low Voltage (LV) switchgear carrying out phasing tests when they identified unusual voltages.

They returned to the HV switchgear and under access permit conditions carried out investigations and found the pig tails on the fuse holders were jammed into the fuse canisters which had caused the HV fuses to operate

What happens now?

All EFACEC pig tails on the HV fuse holders must be checked prior to commissioning to ensure they are free from obstruction, in a normal designed position and are not jammed into the fuse canister.
