    Alternator protection in case of fault at armature terminals

    In case an alternator is running at no load and there is a 3 phase fault at its output (armature) terminals. What protection comes into play to protect alternator from supplying the fault?

    difference in motor and transformer used for 230V, 60Hz system and 415V, 50Hz system

    According to this equation (N*A*B)US < (N*A*B)India If B and N are same then AUS < AIndia therefor U.S. devices are smaller

    difference in motor and transformer used for 230V, 60Hz system and 415V, 50Hz system

    What is the difference in the design of transformer and motor (core and windings) in US (230V,60Hz) and India (415V, 50Hz)?

    50Hz, 415V and 60Hz, 220V system

    How are losses and core size and lamination thickness different in the two cases for transformers? At some places I have read that core losses increase in case of 60Hz. But I think it should decrease in case of 60Hz.
