I think you need to sit down with your calculator and revisit some of these sums and your testing..... if you have a Zs of 3.35 when you have a Ze of 207, then that means you have an R1R2 value of -203.65. Now that's a cable I'd really love to know where to buy.
The low pfc values that you get on TT installs are part of the reason for the requirements for RCD protection; it is realised that you will never get anywhere near disconnection times with that little current.
To lower your Ra then as others have said, bang in some nice LONG 5/8 rods down to at least a couple of metres.
.it's still hit and hope with me, luckily or hopefully more like, I want my days of fitting rods to be of a minimum now, but never say never ...............fancy some scratchings with that beer ???
Re adding a rod: If you go that route it will need to be at a distance away at least 3 times the length of the existing rod
Sorry my typo : r1+r2 of 3.35. lol
think im gunna just put longer rod in . yes they are covered by rcd od course ( dis times etc) just trying to keep costs down for customer ( single mum ). doing this will enable the continued use us existing bonding . therefore wont hav to ripp up her laminate flooring to run new 10mm.
Conversion to PME will mean upgrading , therefore cost and damaged flooring.
