    Abstract - (Show below) - (Hide below)

    Concerns requirements and tests, in addition to those given in chapter 1 of IEC 60185, that are necessary when inductive current transformers are used with electrical protective schemes in which the prime requirement is the maintenance of a defined performance up to several times the rated current when the current contains an exponentially decaying d.c. component of defined time constant.
