Reclassification of the loss of Wagga 132kV B bus, No2 and No3 transformer as a credible event 11 June 2016
AEMO ELECTRICITY MARKET NOTICE
Refer AEMO ELECTRICITY MARKET NOTICE 53874
At 0950 hrs on 11/06/16, the Wagga substation 132kV B bus, the No2 and the No3 330/132kV transformers tripped.
The cause of this non credible contingency event is not known at this stage.
AEMO is not satisfied that this non credible event is unlikely to re-occur.
AEMO therefore classifies this event as being a credible contingency event.
The No3 330/132kV transformer and the bus were placed on load from 1430hrs, the No2 330/132kV transformer remains de-energised.
