I'm trying to determine the zero sequence impedances for a T-model of a step down transformer so that I can perform phase to ground short circuit current calculations on the low voltage side of the transformer but i don't understand the H-L%, H-T% and L-T% format that the manufacturer supplied...
I know it's not commonly done but is it acceptable according to the Canadian Electrical Code (or American Electrical Code) to connect live wires to the bottom instead of the top of a non-fused rotary disconnect switch (Socomec model 27003021; Link to website...
