PME earth electrode found under pavement

PME earth electrode discovered under the pavement.......So they DO exist.....

You must be right next to the pot end, they are on the end of every CNE cable (3phases plus combined neutral/earth on a PME system

On WPDs network, every joint on the main has to have a ‘pigtail’, a coil of copper wire left in the ground. Apparently they don’t put rods in any more after a few near misses!

Every service alteration I see done involving a joint has a pigtail and a length of hard drawn bare copper run in the trench.

This is part of SSEN procedure too, has been a thing for 6 or so years now, wasn’t done when I did my training though!

Were these 'near misses' the worst they experienced, or did they also have some 'hits'?

One did involve striking a like 11kv main. Allegedly the jointer didn’t even feel a tingle

Well according to a now retired linesmen I worked with who had received an 11kv shock via a tree that was leant on the live overhead, it doesn’t shock it ‘crawls through you’

Depending upon how much, and what parts of the tree were involved, i suppose that the path might have had quite a high impedance -such that, despite the 11 kV 'driving voltage', the actual magnitude of the shock (current) might have been 'much more modest' than one might expect, perhaps 'no worse' than an LV shock?
