Power and Water Corporation has completed an upgrade of the Darwin to Katherine electricity network to improve its reliability.
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.
Power Networks’ General Manager John Greenwood said the team successfully completed stage three in Darwin, the final stage of significant work for the Hudson Creek Zone Substation and switchyard upgrade.
“This work was successfully managed and implemented throughout the entirety of the project,” Mr Greenwood said.
Mr Greenwood said in addition to the installation of the visible primary plant at Hudson Creek, the final stage also 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,” Mr Greenwood 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.”
