Brownout? or am i missing something?

[SX2]

Evening all!
Have had a strange problem today my gut is telling me its a brown out! , We are currently working in a old cottage concealing the wiring recently rewired in surface trunking circuit at a time. Around 1500hrs We noticed the lead light (2d) would not start and quickly established a power fault. On investigation I found that as the loading on the system increased the voltage dropped considerably, under no load I was getting around 239v but with around 180watts of incandescent lighting this dropped to 217v turn as 2kw heater on and game over! Everything is rcd with no nuisance trips, all but one circuit is above 50 Mohm with the other at 2.4 Mohm so no problem there! have tried all circuits independently the only common denominator is load. Having never experienced this with a mains system I feel a little stumped. the cottage is remote and at the end of line from the nearest transformer, any thoughts?

Many thanks!

Chancers are it is a DNO fault , especially today ! You need to do as Glen says and check at the incomer , if it is here as well then there is not much more you can do yourself .

Poor neutral connection in the supplier's joint box under the drive/pavement. I'll put a pound on it. Daz

I think it is an overhead straight to the building though , so my pound may go on it being chaffed where it's anchored to the building.:reddevil:

Yes I had this on a new build, lights dimming when the vacume was turned on ! It was found out to be a loose neutral in service head
