AS 62689.2:2022 PDF Download

AS 62689.2:2022 is a standard that focuses on the system aspects of current and voltage sensors or detectors used for fault passage indication purposes. It is based on and modifies the IEC 62689 2:2016 standard, which defines the behavior of electric systems during faults based on commonly used distribution system architectures and fault typologies.

The purpose of AS 62689.2:2022 is to establish the functional requirements for fault passage indicators (FPI) and distribution substation units (DSU). These requirements include the specifications for the current and/or voltage sensors that are used in these systems. The standard provides guidelines for the design, installation, and operation of these sensors to ensure accurate fault detection and indication.

By adopting and modifying the IEC standard, AS 62689.2:2022 ensures that the requirements for current and voltage sensors meet the specific needs of the Australian market. It helps to improve the reliability and efficiency of fault passage indication systems in the distribution network by providing a standardized approach to the selection and use of these sensors.
