Changes to the New Edition of the HV Installation Standard (AS2067) Part 2: Earthing Safety
AS2067 is the standard that covers the design of high voltage substations and installations. The September 2016 release followed an extensive review of the 2008 edition. This presentation focuses on the changes to the earthing components of the standard, being based on a more explicit use of risk analysis and assessment in line with the new WH&S Act.The reasons behind the changes are given for each aspect as well as the logic followed to arrive at the final results. The impact of the changes and how the new standard is being interpreted and applied will be discussed using case studies, as well as possible future directions.
