Abstract

This project is an investigation into a possible fault detection system for SWER (single wire earth return) electrical distribution networks in Victoria that focuses on types of faults that are undetectable by conventional protection systems and have the ability to ignite fires. The paper considers why a new detection system is required and then how it could be practically implemented in a general sense. More detailed investigations then focus on communications, power harvesting and fault detection considerations.

The devices are proposed to be distributed across SWER networks to enact a detection system. The paper focuses on the many conflicting requirements and subsequent compromises that any eventual design will need to overcome. It is found that electric field power harvesting from the Victorian SWER lines’ 12.7kV conductor can produce power outputs within the range required by standalone detection devices given fairly severe design constraints. Summaries and conclusions are drawn to a level where the project develops a clear methodology to go forward.
