Second circuit breaker energised and in service

Power and Water Corporation’s major equipment upgrade for the Hudson Creek Switchyard

The third new 32kV circuit breaker is now energised and in service as part of Power and Water Corporation’s major equipment upgrade for the Hudson Creek Switchyard, in the Northern Territory.

The installation on August 20 completed the 2014 program, with further circuit breaker replacements scheduled as part of the 2015 season intensive maintenance and upgrades strategy.

General manager of Power and Water Corporation, Northern Territory’s primary provider of electricity, John Greenwood said the second phase follows the successful installation of the first new circuit breaker in early August, with equally successful results.

“It has responded perfectly to all our testing and measurement procedures and is now a functioning part of the switchyard,” he said.

“Replacing 132kV circuit breakers is a challenging process and creates an element of risk to the system however, these works are designed to improve the security and reliability of the 132kV power network.”
