Australian Standard AS 2067:2016 Substations and high voltage installations exceeding 1 kV a.c is out now. Get your copy here: http://infostore.saiglobal.com/store/Details.aspx?ProductID=1880642
The standard provides common rules for the design and the construction of electrical power installations in systems with nominal voltages above 1 kV a.c. and nominal frequency up to and including 60 Hz. The new edition of AS 2067 addresses a range of issues including fire risk related to substations within or near buildings and recognises changes in the National Construction Code. It also substantially expands on earthing, with reference to the Energy Networks Association’s (ENA) Handbook ENA DOC 025 EG-0.
Numerous changes have also been made to bring the document closer to IEC 61936, the relevant international standard on power installations exceeding 1 kV a.c.
While existing installations are not automatically required to comply with the changes to this standard, all installations should be reviewed.
Important changes to note:
- AS 2067:2016 contains all-new earthing requirements
- The earthing section of AS/NZS 3007:2013 now defers to AS 2067:2016
