What are the loads doing? Is the transformer on fire?
there is a fusable disconnect that this panel is feeding... this panel is being fed from a 480 to 120/208 transformer... as far as the fuses in the disconnect, i checked the fuses and they are good
no... transformer is not on fire
upstream...havent heard that term... but lemme know and i can check it for u
I was thinking that 1 and 2 shorted together, and one of the primary fuses blew
Look out at the pole that feeds your transformer, see if any of the cutouts are hanging down open
the transformer feed is good... phases read
these readings were taken from the legs that feed this transformer... these legs are in a panel on a breaker that feeds this transformer
How about the voltages on the secondary side of the step down transformer? Am I correct in assuming your first voltage readings were taken at the 208 panel?
think i found the short ... so my xo line in the transformer is burned and almost melted and is really loose and sparks to the touch at the tap...this is in the transformer that feeds the panel that drops 1 to 2 phase
yes ur assumption is correct
Photo's?
i tried but it says file is to big... imma try to upload photos
heres a photo of the lines and u can see the melted line
heres a close up view
