I know some countries use protection to guard against a broken neutral in PME systems.
Anyone know how they work?

Acording to E54 it never happens, so why bother.I know some countries use protection to guard against a broken neutral in PME systems.

Speak to the DNO ask them if you can fit an Earth Rod as a back up they will probably say no but do it anyway lol

Most of the underground PME joints to supply buildings are staked by the dnoThat is the way it is done in some countries an external electrode is connected to the N / E juncture within the service head.

I don't quite get where he's saying it should be positioned in relation to it's effectiveness ? My CU has a 30mA non delayed RCD as a main switch will it trip out if the N drops out ? it's the same as his diagram isn't it ?

Doesn't the white wire on the RCD help with this?
It happened to my house years back.
I am thinking if 10 houses are on the same phase as me and the N drops off will I get all their fault load as well because my nice shiny new earth rod will provide a lower path of resistance than all their bonded extraneous water and gas ?
