Hi
Today I got out my Megger 1730 that has recently repaired and was trying out the R1+R2 function. I know what the values of all the circuits are in my house as I rewired it last year. I completed a ze test and it came back at 2.97 ohms, bearing in mind this is a tns supply and the readings were 0.29 ohms last year. None of my neighbours were in so I could not confirm if the MFT was faulty by testing others premises.
So I rang Megger Tech support who by the way were very helpful and we talk through various tests and come to the agreement that it needs to be returned to Megger. Big moan by me how crap this MFT is, time now to eat humble pie, I tested several neighbours houses tonight. My MFT is fine, the Ze on my premises is now crap and so is one of my neighbours premises, I guess the nice people digging up the road have nicked the earth as the DNO came out the same day and confirmed my findings, they are now going to dig up the road.
I must ring up Megger tomorrow and say thanks to the Tech support as they were going to send me a temporary MFT while they repaired mine. I did say I would check other installations tonight to confirm if it was my MFT was defective or my earthing arrangements.
The moral of this story is I wont be using the R1 R2 feature on this MFT
