My point was that it may not be PME at all. Where are those multiple electrodes and what are they achieving?If you look at the ESQCR regulations, there only needs to be two earths to make a PME supply - one at the substation end, located at or before the connection to the first service connection, and at the far end of the PME distribution main, at or after the final service connection.
Well yes, 2 > 1 = multiple, but the reality is that we don't know where those electrodes (if any) are situated. What I don't quite understand is that if the water supply is through a metal pipe, why has it not pulled the surface potential towards the distributor's earth.
