Broken T/X or Bridge?

[BillyMac]

Well here goes.....two liney's on call recived a call out to a house with low volts after doing some test's they narrowed it down to being a dud single phase tranny but by this time they were due for stand down, that's when me and a couple of fella's rock up the next day to change the tranny for them (you find it you fix it I reckon), shit of a spot, no access for bucket truck so all done off a ladder and changed T/X with a herbie and winch. Come time to commission t/x closed in EDO's and proceeded with voltage checks same problem used modiewark and there seemed to be 11kv on both phases up top but no 240 coming out,surely not two dud tranny's especially this one being a brand new ABB. So we's decided to preform a line patrol and low and be hold a burnt off bridge on the take off pole a tricky one to spot as there were no other call's from customer's that night on that tee-off (later found out only a farm house and pumps- no one home). So there was not really 11kv on both phases up top just the one but returning back threw the system. We all learnt a valuable lesson that day Has any one else come across this?
