Driven by accurate EFD™ data and visualization tools, a cracked glass insulator was remotely located on Victorian distribution network, and the problem was identified on the site utilizing acoustic and optical cameras.
A cracked glass insulator forms conductive paths from powerlines to poles that can lead to hazards for communities and the environment such as electrical faults, short circuits, and fires. From the picture above, tracking paths can be seen on the insulator, indicating a structural damage.
Accurate data monitoring, remote diagnostics and early fault detection capabilities of EFD system have revealed this tracking insulator with pinpoint accuracy before a hazardous event happened. This insulator fault would be difficult to find with the traditional routine inspections.
With EFD system, potential risks are identified before they turn into problems, improving system reliability and eliminating the risk of fires, environmental and reputational damage that come with it.
