Oh Rob, surely just a little lick with the end of your tongue, it would be like a 9v battery

I used to get readings like that all the time in the factory I used to work.
These were still a hundred yards or so from the Txs but due to the size of the submain cables to the switchgear and busbars and steelwork parallel paths there remained very low impedance/high fault current potential !

Mine were Line to Earth 
I've had a 0.01Ω line to earth a few years ago in an old mill.
The switchroom backed onto the substation, and the incommer was around 195mm²

When my Alphatek flags up 0.01 Ohms, I usually think it's lying & press "start" again...!
