Lightning is one of the most common weather occurrences, with thunderstorms producing about 6000 lightning strikes worldwide every second.
Last week’s storm shows how lightning can play havoc with the electricity network, with weather-related power interruptions recorded across much of the State.
Country Energy’s regional general manager for the north western region Pete Halliwell said lightning was attracted to the overhead power network because of its height and the nature of the energy travelling along the wires.
“While your toaster uses about four amps, the average lightning bolt carries a current of up to 30,000 amps and it can, and often does, strike the same place more than once,” he said.
“When lightning strikes the electricity network the damage can be extreme, with poles smashed so they resemble toothpicks, transformers and insulators destroyed and bringing powerlines down.
“We rely heavily on members of the public to let us know of any low hanging wires or damaged poles. It helps us pinpoint where our problems are to fix them.”
Country Energy recommends electrical appliances or wired telephones are unplugged from the power point during a severe storm, including sensitive equipment such as computers and televisions.
“Keeping people safe is our top priority,” Mr Halliwell said.
“Customers can be assured that if power is cut because lightning strikes, Country Energy’s network and our crews will be out working to get the power back on safely and as quickly as possible.
“Stay well clear from fallen powerlines as they could be live, and report any network damage or safety hazards to Country Energy’s supply interruption line on 13 20 80.”
Lightning is hard to prevent damaging the power system, but measures are in place to safeguard the network and prevent power interruptions, such as surge arrestors and lightning rods which act to direct electrical energy from lightning bolts to the ground.
“To identify where a thunderstorm is and its approximate intensity, you can use Country Energy’s ‘stormtracker’ which traces storm activity across the State,” Mr Halliwell said.
“It is updated every 15 minutes.
“People may find it useful to see if they should take precautions in case of a severe storm.”
