PowerEarth was involved with the earthing system commissioning testing on new infrastructure built for the Gawler Electrification Project, South Australia.
The Gawler Electrification Project involves the electrification and modernisation of the primarily diesel fed Gawler rail line to deliver a faster, cleaner and more reliable service, delivering an electrified network through Adelaide from Gawler to Seaford.
Once complete the electrified line will support increased capacity and future growth for development along the rail corridor and in northern Adelaide.
Off-grid frequency and current injection testing was performed on the earthing systems at a number of new sites built as part of the Gawler electrification upgrade works in South Australia. This included the Adelaide City track sectioning cabinet, Dry Creek Feeder Station and Munno Para track sectioning cabinet.
Various parameters of the earthing systems were measured including current distribution, soil potential profiles, touch voltages, step voltages transfer and earth potential rise.
Results were analysed and evaluated using our CDEGS software to verify the site test results accuracy and deliver detailed commissioning test reports to evaluate the infrastructures fit for energisation status.
