how sensitive are step-downs

[reppy007]

I cant be the only one that has seen this happen,so Ill give you the short version of the story as I remember it,and see if others have had similar situations.Years ago we had a tropical storm blow in which was called Allison,it produced more rain then any hurricane I have ever seen...a day or two after the storm we were sent up to the northern portion of our area to get lights on.this one area was a little hilly and there happened to be a few urd loops that were fed by step down transformers.19.9/7200.....being hilly meant that there also were some low areas and there was no shortage of live-fronts....keep in mind that there was still plenty of water in the area and in those low areas.....well believe it or not there were guys shooting the step/downs,and what was happening is that they were burning them up left and right,due to faults on those loops or the high water,and the usual bad wire under the red hoods....it took alot of yelling to finally teach these guys that shooting them and replacing them wasnt the right solution..........its been my experiences ,and there are a few that the step down transformers are really sensitive,seems like more than the usual transformers to me,whats you guys take on this one?
