Earth/Neutral fault..Help Needed!!

[Cid]

Probably a shared neutral somwhere. Neighbor?

Is it a converted flat?

Hi,i'll be honest,if i was attempting to explain a situation to a customer,in a property with a suspected earth issue,disconnecting the neutral tail,and leaving the line connected,would not be a method i would choose.

This is a situation,which would be considered dangerous,in an older property,where earths at origin,may be poor,and an original fused neutral,had blown.

Any good advice to give, you have taken the time to post 3 times on this topic but every post is irrelevant to the question I asked?

I too do not like irrelevant or negative coments when asking a legitimate question, but I think you need to re read pegs posts as they are relevant and I couldn’t detect any negativity other than stating concern over a potentially dangerous issue.

In the past we have had on this forum, if you don’t know you shouldn’t be doing it. It’s changed.

all the posts have been in order to help. Re read them.

I think all 3 of PEG's posts are relevant.
Re PEGs last post, it's covered by the very first line of your O.P

Probably going to get slated for not knowing/doing something wrong but here goes!!

Then you mention Dead testing but as you have 170v it's not dead.

Have you actually verified Ze as suggested in #2. A random test at a socket will prove nothing.

The best advice I'd give to start with is that you stop creating dangerous situations by disconnecting the neutral of a live installation.
As lucian has pointed out this will have diverted the load current via the fault to earth and potentially caused a lot of damage in doing so, not to mention the significant danger to your life and that of anyone else in the property.

How does this explain disconnecting the neutral tail coming out of the meter and the board still being live across L-N?

Oh dear. You need to read it again.
You've made no mention of isolating the incoming L so we have to assume that's at around 240V relative to earth and incoming N.
You've disconnected the N.
You measure between the 240V L and something that is now "sort of floating" with various resistive and capacitative paths (one of which is your meter) to both L and E.
So the N will be at some voltage between E and L - and you are measuring the difference between that and L.

This thread is making my head hurt. I've read it start to finish and back to front. Still can't work out what the heck is going on

Hi dude,i apologise if i have offended you,but your original post title,was regarding the earthing. You were asked several times,including by myself,regarding this,and got no answer.

I am sorry you think my points regarding the safety aspect of disconnecting and then demonstrating,are irrelevant....this is a worry.

I wish you well and success in your quest,but as the great Deborah Meaden said....i'm out?
