Braemar Voltage Exceeding Satisfactory Limit - 09 October 2009
At 14:02 hrs on 9 October 2009, in an effort to increase the 11kV distribution network voltage, the Kogan Creek generator terminal voltage was raised from 21.2kV to 21.7kV. This resulted in the voltage measured on the 275kV bus at Braemar substation reaching 302kV and exceeding the satisfactory limit of 301kV for approximately 6 minutes.
Powerlink and CS Energy have investigated the incident and are taking steps to mitigate the risk of similar incidents occurring.
