    Secondary fault current in open delta configuration

    Can anyone point me towards a reference or thread that explains how to find available fault current on the secondary side of an open delta bank? I have a 75kva and a 37kva open delta bank and would just like to calculate available kA. Thanks

    Motor short circuit contribution

    How do you calculatie motor short circuit contributions? I know that C37.010 and 013 give impedance multipliers. For a 100hp motor the first cycle calc is 1.2*Z" but how does this translate into a short circuit current? Doesn't the motor kV come into play?
