House is 1 year old. POCO single phase line is 1.5 years old and crosses under a 345kV AC transmission line.
Homeowner reports tingle when touching the refrigerator while standing on floor in bare feet. Floor is stained concrete.
Voltage from metal parts to floor was less than 1 volt. NEV at POCO transformer pole was 3. POCO ground resistance measurements were 20-30 ohms at each pole which I found surprising that they would be that good.
With POCO transformer open, there is still objectionable voltage.
The conductors going to house were separated from POCO and all was good. No complaint.
The house is in a rural setting with no electrical inspection during construction. The EC did run four conductor secondary but neutral and grounding conductor are not separated in panel at the house wall. 2/0al for neutral and a green 6cu for ground but they are in parallel. PVC from water well to house, house is done with PEX. I did not see a bond on water heater nipple.
My first instinct is the mistakes I see suggest EC not familiar with any code and the slab rebar is probably not bonded.
The questions are;
What effect can the 345kV have on the property and if slab was bonded would there be a voltage difference between the bonded metal appliances and the concrete floor?
