(1 - 2) Please refer to [Tabled Paper No.]
(3) A number of approaches are being enacted to minimize the impact of lightning, including automating specific equipment, increasing power quality monitoring and recording, and implementing routine inspection and maintenance activities for that area.
Targeted refurbishment work has been planned for the feeder starting from 2012/13 FY with all the stages of work expected to be completed by 2014/15. This includes
· installation of 61 km of overhead earth/shielding conductor that will minimise the impact of lightning
· additional automated equipment to facilitate faster isolation of faults, automatic restoration following an interruption and capability for greater remote monitoring and control
In addition to the above, the refurbishment work will provide added benefits that include:
· improving public safety by rebuilding sections of the relevant feeders which have come to the end of their useful life;
· reducing the risk of fire resulting from asset failure;
· improving reliability by reducing the risk of network outages;
· minimising the outage duration; and
· achieving better customer service outcomes.
To reduce the occurrence of interruptions from equipment failures, pole reinforcement and replacement programs are also being progressively carried out along the Moora network. Western Power will continue to undertake routine maintenance and inspection to identify poor performing assets and carry out corrective works as they are identified.
