The mother of a girl who was left severely brain-damaged from an electric shock at state-owned housing in Perth has called for a public education campaign to warn about the dangers that almost killed her child.

Denishar Woods was shocked with up to 230 volts when she touched a garden tap at her family's Beldon property in March last year, leaving her wheelchair-bound, effectively blind and unable to do anything for herself.

Then aged 11, she was initially not expected to survive.

A report into the cause of the shock, released on Friday, concluded a neutral conductor on a cable supplying electricity to the house had failed after prolonged heating, causing the tap - which is connected to the protective earth system - to become electrified.

Ms Harrison had called Housing Direct After Hours Emergency Call Centre less than half an hour before the tragedy to report that she and two of her children had suffered electric shocks when they touched the metallic switchboard enclosure.

Six months prior, one of Ms Harrison's children received a "tingle" from a bathroom light switch, which was replaced.

After Energy Minister Bill Johnston urged anyone who experienced shocks or tingles from fittings in their homes to report them directly to Western Power immediately, the mother-of-seven called for a public education campaign.

She also urged the state government to pay compensation to cover Denishar's substantial ongoing care.

"Money is not going to fix or help my daughter get better in any way other than having access to physiotherapists a lot more than what we get, and speech therapy and occupational therapy.

"But this is every day for the rest my life - I am stuck here. I can't go and get a job. I am so committed to this little girl's everyday wellbeing."
