Spotswood DC

WORKS: External Earthing Upgrade

Client: VicTrack


Scope of Works

A review of the initial DC earth electrode system has highlighted a need to upgrade the system to provide a more robust and lower impedance electrode system for the site.

Six new earth electrodes will be installed along the eastern perimeter of the property, and connected to each other via a galvanised earth strap.

This upgrade will reduce the impedance to earth to approximately one eighth (1/8) of the current system.

No internal changes are required as part of the upgrade works.

** Works refined to include trafficable pits
