The Powerline Bushfire Safety Program (PBSP) approved a grant in April 2018 for the development of a protection device that can detect a break in a Single Wire Earth Return (SWER) overhead conductor and send a trip command to de-energise the circuit before the conductor hits the ground.

The objective of the project is to:

  • Develop a prototype to ascertain whether the device is capable of detecting a break in a SWER overhead conductor; and
  • Speed up the development of a potentially cost-effective product that may be commercialised and used on the Victorian network.

The project is due to conclude in June 2019.
