Reports support using REFCLs
to reduce bushfire risk
By Nathan Bitsas, Team Leader, Bushfire Mitigation
Two recent reports support the use of a technology that reduces
the risk of powerline faults causing catastrophic bushfires.
Energy Safe Victoria (ESV) released the independent reports
on Rapid Earth Fault Current Limiters (REFCLs) in January.
REFCLs detect faults in powerlines
and greatly limit the energy at the fault
location, reducing the risk of a spark
causing a fire. However, if the fault is
ongoing, such as a fallen or broken
powerline, the REFCL instructs the
circuit breaker to switch off power to the
entire powerline until it can be repaired.
ESV commissioned two independent
reports on REFCLs – a cost benefit
analysis and a performance report.
Although the technology is not new,
it has not been used this way. It is a very
technically complex and specialised
field. Although the technology is proven,
ESV is monitoring and assessing its
performance as it is implemented
Victorian REFCL Network: REFCLs are gradually being rolled out across Victoria across Victoria.
ESV commissioned the reports to gain
independent assurance that this world-
first application of REFCLs benefits the
Victorian community, works as well as
it should and that all issues are being
managed.
Cost-benefit analysis
The report said that calculating the
benefits of any bushfire mitigation
program was difficult, and used the
Black Saturday bushfires in 2009 as
a basis for calculating the costs of
catastrophic bushfires.
The REFCL cost-benefit analysis report
by the Nous Group found the benefits
of the technology are much higher when
community costs are included in the
overall cost of catastrophic bushfire.
