NS230: Testing of Distribution Substations

NS230 applies to the testing of new distribution substations throughout all parts of Ausgrid’s supply area. This standard is applicable to pole, kiosk and chamber substations.

Scope

This Network Standard is intended for the testing of new pole, kiosk and chamber distribution substations.

For existing substations, authorised Ausgrid staff may decide which tests are appropriate during the augmentation. Tests selected from this Network Standard, for augmentations, shall depend on the specific substation changes completed during the works. Alternative test voltage levels and limits may be applied where appropriate, to previously in-service equipment.

Testing methods within this Network Standard supersede those in the following standards:

• NS114 Electrical Design and Construction Standards for Chamber Type Substations
• NS117 Design and Construction Standards for Kiosk Type Substations
• NS122 Pole Mounted Substation Construction.
