One of our customers is having a problem while they want to energize a dry type transformer 2/2.8MVA 13,2kV Delta - 480/277V Wye. It is for a commercial building and the fuses blow at the moment they want to energize. Some people says it could be the inrush current and sugest to increase the ampacity of the fuses. Any comment or idea? Why not with oil filled pad mounted units?
Thanks!!
