This is a hypothetical question and is based on thread238-246755. There it was established that the rating (amperage wise) of a transformer secondary was meant to be interpreted as being 600A in each phase or line.
Say for a moment, that this transformer was a delta-wye, 500 kVA, and is...
In selecting the proper size feeder to a transformer, should I consider the type of load the transformer feeds or should I just go by the primary current required? I am curious if one ever considers that the load may or may not be continuos or non-continous. I have a 3-Ph, 480V-208/277V, 45 kVA...
I need to power 16 double-wide trailers, each at 120/240V and each double-wide having 2-100A single phase panels. I have a 13.8kV supply. I am thinking of a 3-phase 13.8kV-480/277V dry type Xfmr and then split up phases to feed three single phase 480-120/240V Xfmrs. However, I believe that if...
I am stumped on what seems like a fairly simple calculation using a spreadsheet. I have four vertical user boxes for input of variables. Call them C21, C22, C23 and C24. In C25 I have an equation that uses information from the previous four cells to calculate an answer for C25. Then I have...
