Hi Mark, yes so far so good but if the PME system is unsafe in the event of a neutral failure how come the electricity supplier installed it, there must be many thousands installed in the UK especially in rural properties? shouldn't they have installed some cut out device in the event of such an occurence.
Interestingly we had a rarther alarming garden fire here last year, basically what happened was that the old aluminium uninsulated twin feed from the transformer started physically oscilllating causing the live and neutral to clash thus sending white hot lumps of aluminium showering down in several places in the garden, the grass was very dry after a prolonged dry spell, it instantly caught fire in no less than six places at the same time. It was caused by a horse rubbing it's bum on a stay wire on the pole the transformer was fixed to, the power company were immediately notified by myself. They came out and replaced the line with a twisted insulated cable. I asked if they were doing this to all the old uninsulated twin wire lines, they said no, only when they get a call out, negligence or what.
If that had happened at night the whole place could have caught fire unchecked, beggars belief really.
