Power and Water finish the Darwin to Katherine upgrade

Stage 3 of works on the Darwin to Katherine network has been finalised, completing the entire upgrade project.

Power Networks general manager John Greenwood said the team completed the final stage of the major work for the Hudson Creek Zone substation and switchyard.

“The project involved the replacement of six critical 132kV circuit breakers, the installation of a new 132kV plant at Hudson Creek as well as the upgrade of secondary protection systems,” Mr Greenwood said.

Mr Greenwood said in addition to the installation of the visible primary plant at Hudson Creek, the final stage involved the replacement and upgrade of the power system protection schemes.

“The protection schemes detect power system faults and operate the system automatically and within milliseconds in order to maintain a safe and reliable power system,” he said.

“These monitor the two critical transmission lines between Channel Island and Hudson Creek and the work was complex, requiring careful design, testing and installation.”
