Published By:International Electrotechnical Commission (IEC)
This part of IEC 44 covers the requirements and tests, in addition to those in Chapter I of IEC 185, that are necessary for inductive current transformers for use with electrical protective schemes in which the prime requirement for the current transformers 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.
