Hey guys, Been struggling with this for ages any help would be awesome. In Electrical engineering; Suppose you have a balanced multiphase star system with a given line voltage. The impedance of each phase is also know. If one of the coils is short circuited, calculate the line currents. I'm assuming the two remaining phases are 90degrees apart so that the line voltage remains constant between all 3 remaining nodes. Also that the phase and line voltage of the remaining nodes are equal. Is this correct? I cannot understand why there are two different line currents? Shouldn't these both be equal to the line voltage divided by the impedance?
