  • Abstract
    Some conditions which have to be met with in protecting transformers by the usual current-differential method produce special problems. Those involving the protection of interconnected wye or zigzag transformers and those involving Scott-connected transformers are dealt with at some length. There is also a discussion of tolerances in the selection of current transformers and the factors to be considered in the selection of relays for the purpose.
