The object of this Technical Report 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. This technical report cancels and replaces International Standard IEC 60787, published in 1983, and constitutes a technical revision.
