IEC 60044-6-1992 Instrument transformers - Part 6: Requirements for protective current transformers for transient performance

Language: English, French
This part of International Standard IEC 44 has been prepared by IEC Technical Committee No. 38: Instrument transformers.
This part of IEC 44 is to be read in conjunction with IEC 185 and its Amendment No. 1.
Annexes A, B, C, D and E form an integral part of this part.
Scope
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.
