NS238: Supply Quality

Ausgrid operates an extensive network which brings the electricity supplied by your retailer to your home or business. 

Our aim in this document is to:

• provide tips on how you can protect your electrical installations and your electrical equipment and appliances connected to our network from the potential problems that unprotected equipment can suffer because of variations to electricity supplied through our network, and
• help you understand the operating environment of our network, and explain why the electricity
  supplied through it has particular characteristics.

We set out Ausgrid’s objectives for the impact that our network has on the characteristics of the electricity supplied through it by your retailer.

This Network Standard is in two parts. Part A (Section 5) is designed for the general reader. Part B (Section 6) is for use by specialists, and contains technical material in technical language.

Scope

This guideline states Ausgrid’s objectives for its electricity network’s impact on the characteristics of electricity supplied by retailers to their customers through its electricity Network. It replaces the Electricity Network Operation Standards (ENOS) document.

This document is intended for use only by customers who are connected to Ausgrid’s electricity network and should be read in conjunction with the following publication issued by the ENA (Energy Networks Association), which provides definitions and information essential for understanding this document: 

• ENA Customer Guide to Electricity Supply.
   
  The latest edition of this document is available on our website www.ausgrid.com.au.
  
  In stating its objectives for its network, Ausgrid does not include:
   
• interference originating from a customer’s installation that adversely affects the installation and equipment of that customer or other customers; and
• events or incidents associated with generation or the transmission grid. 

Although Ausgrid intends to use all reasonable efforts to address departures from the objectives specified in this standard, there could be circumstances which affect Ausgrid’s ability to meet them.

Accordingly: 

• each objective must be read subject to the limit of liability specified in the Contract; and
• this document and the ENA publication referred to above do not constitute a representation or warranty by Ausgrid that the electricity supplied by retailers to customers through its network will be of a particular quality, or that it will be available at all times.
