Voltage standards review 2018

This review focused on amending the Electricity Distribution Code to allow for the operation of Rapid Earth Fault Current Limiter (REFCL) technology to prevent bushfires.

We have now updated the code

Changes to the code enable use of REFCLs at 45 high voltage substations in high risk fire areas across Victoria. The introduction of the technology was an outcome of the 2009 Victorian Bushfires Royal Commission and subsequent new bushfire mitigation regulations.

The amended code allows for future installation of REFCLs at additional sites on the high voltage for safety and other purposes provided this is approved by Energy Safe Victoria.

The changes to the code came into effect on 20 August 2018.
