How do you calculate total 3 phase current draw?

WebApr 7, 2013 · \$\begingroup\$ If you have control over the placement of the existing voltage meters, remove them from the delta formation they are in and connect them across neutral and each phase. Multiply the voltage for each phase by the corresponding current and add the three together. (Note that you don't "lose" the phase-phase voltage measurements … WebNormally, short circuit studies involve calculating a bolted 3-phase fault condition. This can be characterized as all 3-phases “bolted” together to create a zero impedance connection. This establishes a “worst case” (highest current) condition that results in maximum three phase thermal and mechanical stress in the system.
