NS114: Electrical Design and Construction Standards for Chamber Type Substations
This Network Standard specifies Ausgrid’s requirements for the electrical design, construction and equipping of chamber type distribution substations, for supply of electricity to premises. The requirements of this Standard shall apply throughout Ausgrid’s supply area, for contestable and non-contestable projects.
Scope
This Network Standard:
- applies to nominal 11kV primary voltage systems
- applies to nominal 400 / 230 volt distribution systems
- applies to chambers used for control points and for control of supply to high voltage customer
(HVCs) connections - does not apply to SWER systems
- does not apply to nominal primary voltage systems higher than 11kV
- does not apply to zone or sub-transmission substations, 11kV regulators or auto transformers.
Substation civil design and civil construction are not covered in this Standard. These topics are covered in NS113 Site Selection and Construction Design Requirements for Chamber Type Substations.
