I was simply stating what the plan was going forward. I appreciate all of the insight and don't understand the criticism. Thanks for the help in getting this resolved.
Couple of things I found today from my electrical contractor and by me making a general observation on the system.
1.) The type of fuse cutouts are QA
2.) The secondary ground and primary neutral are tied together at the pole where the transformers are mounted on several but not all of the...
BTW waross when one phase is lost due to a main blowing, two of transformers try to do the work of three causing low supply voltages. Usually something like:
Line to Neutral - 105
Line to Neutral - 204
Line to Neutral - 105
Line to Line - 215
Line to Line - 225
Line to Line - 230
waross - my concern is although our demand is relatively low for the size of primary lines we have ran, our contracted high voltage electricians continue to increase the size of the fuses.
As mentioned above I will gather more details in the morning on the fuse type, etc. I don't think I...
Magoo2 - I am not sure I can answer that question but I think they are connected grouned wye. The only reason I make that assumption is because we have a 4 wire primary.
PHovnanian - I would say that this situation is a bit unusual because we are processing explosives. There are mulitple...
Good Morning -
I have been faced with a problem for over a year and am seeking insight from professionals on this topic. Any help would be greatly appreciated.
