Noorat resident Tyna Murray was shocked to discover the transmission line on Cliffords Lane resting on grass while out jogging on Thursday morning.

"We couldn't believe it," Ms Murray said.

"The arm has completely snapped off. How it didn't start a fire, you wouldn't know."

Ms Murray said she was concerned about a repeat of the issue in future.

"It's really scary," she said.

Member for Wannon Dan Tehan has called for an immediate independent investigation by Energy Safe Victoria.

"It took the state government months to act to make sure these unregulated lines could not get built again," the federal education minister said.

"We currently have an unregulated line that is clearly not safe in our community.

"We need action through the state government to immediately launch an independent audit on this powerline.

"It can not be left to Ausnet to regulate itself, that is absolutely unacceptable," he said.

Corangamite Shire councillor Helen Durant said the risk to the community was unacceptable.

"I question the quality of the materials used," Cr Durant said.

"Who's to say this won't happen again."

Cr Durant said the transmission line and associated infrastructure needed to undergo an immediate inspection.

Geraldine Conheady, who has been vocal about the lack of planning requirements for transmission lines, said the incident could have led to a fire or put drivers' safety at risk.

"It's concerning - not only because it could have started a fire, but what if someone was driving along that road at the time? The regulation is just so poor. The Andrews government is approaching the construction of wind farms and transmission lines in a kamikaze sort of way - they don't care about how these projects are impacting communities," she said.

Mrs Conheady said she believed the powerlines should be required to go underground.

Terang's Jennifer Jackson said she was fearful the transmission lines would spark a fire.

"This is placing us at risk of a repeat of the St Patrick's Day fires or the Ash Wednesday fires before them," she said.

Mrs Jackson said the main issue was the lack of planning requirements for the infrastructure.

She said she believed the company should be forced to put the transmission lines underground.

"What Tilt Renewables did is a blight on our landscape and it's clearly dangerous," Mrs Jackson said.

Victorian Energy Minister Lily D'Ambrosio said she had been made aware of the incident.

"I understand the concerns of the local community about the safety of powerlines, particularly given we are not out of the fire danger season yet," Ms D'Ambrosio said.

"I am advised that while the powerline was not live and did not pose a safety risk, Energy Safe Victoria along with Ausnet, who own and operate this particular powerline, are investigating the incident."

An AusNet Services spokesman said there was an issue on the power line connecting the Salt Creek Wind Farm and the Terang terminal station.

"The network safety protection system operated as designed in this instance, with no reported damage to persons or property," he said.

"We currently have crews on the ground investigating the fault and initiating repairs. We are engaged with Energy Safe Victoria as the safety regulator and we will assist them with whatever actions they deem appropriate in relation to this incident."
