Network Diagrams

The Network Diagrams include NIPS, SIPS, SPD Drawings and Substation Locators and are contained within the System Operator section of our website.

Relay and Instrument Diagrams

Relay and Instrument Diagrams are for individual substations and show a high level of detail.

To make available the latest relay and instrument information, a diagram may be unapproved by Transpower. An unapproved drawing is for information only and is stamped UNCONTROLLED COPY and should be used with caution.

They should be used when any reference is required for switching, making safe, and other operational actions that can affect personnel safety or power system security.

Single Line Diagrams

The Transpower Regional  Single Line Diagram defines Transpower and our customer asset ownership/operational control boundaries and connect groups of substations.  These diagrams have guideline status only.

The Transpower substation Single Line Diagram (Operating) defines Transpower's operational assets (and customer operational assets where the SLD is of mutual interest). Only the Operating SLDs must be used for reference required for switching, making safe and other operational actions that can affect personnel safety or power system security.

Single Line Diagrams are updated within a month of the changes occurring on site.
