scope:

IEC/TR 60787, which is a technical report, serves as an application guide to the use, for distribution transformer circuit applications, of fuses complying with the requirements of IEC 60282-1: High-voltage fuses;Part 1: Current-limiting fuses. Therefore, this document is informative, not normative. The object of this application guide is to specify criteria for coordination of high-voltage fuses with other circuit components in transformer applications and to give guidance for the selection of fuse-links with particular reference to their time-current characteristics and ratings.
