AS 2067-1984

Specifies requirements for high voltage a.c. switchgear assemblies, indoor and outdoor, employed in connection with the generation, transmission and distribution of electric power and to ancillary equipment used in conjunction with the switchgear. Gives detailed requirements for electrical clearances, safety of personnel, earthing of main circuits, substations and their enclosures. Also specifies requirements for busbars, marking and identification of conductors and terminals, colours of indicator lights, and electrical and compressed air auxiliary systems. Appendices include jointing of busbars and connections, design of earthing systems, and provision of safety clearances.

This standard specifies the requirements for indoor and outdoor switchgear assemblies for alternating voltages above 1 kV such as are employed in connection with the generation, transmission and distribution of electric power. It also applies to the ancillary equipment used in conjunction with the switchgear.It is not intended to cover the requirements for specific apparatus for which separate Australian standards may exist (see Clause 1.3), nor the additional requirements for switchgear for use in mines and explosive atmospheres.It does not give any recommendations for environmental requirements, but these should be taken into consideration in the siting of the installation.
