if the source is a 2 phase, 2 wire system and the load is 3 phase 4 wire, which type of transformer should i use on that configuration? open wye - open delta? 13.8/0.48 kV (1000kVA)
i got to design 5 feeders at 480 V (1000 KVA) for industrial purposes, one of those feeders is at 207 V for offices (3913 ft^2). im having trouble to decide what diversity factor should i use? does anybody know?
the other 4 feeders (480 V) are for welding machines, compressors, and other machinery for construction. in this case does anyone know where i can find typical values of this types of loads?
