[QUOTE="steptoe, post: 355445, member: 7"] thats what I thought, but it seems that Mr Skelton seems that the star point and the impedance has some bearing on this, I just got confused between him intermixing the resistance of the ground with the impedance of the supply, in his instance how would you measure the Ra for [say] a large industrial/commercial building before the supply is available.? is it even possible? is Damian saying that once I measure the Ra it will change once the DNO install their substation.?
