Application guide for the selection of high-voltage current-limiting fuse-links for transformer circuits

This technical report is an application guide to the use, for distribution transformer circuit applications, of fuses complying with the requirements of BS EN 60282-1 High-voltage fuses. Current-limiting fuses. The document is informative, not normative.

The application guide specifies criteria for coordination of high-voltage fuses with other circuit components in transformer applications. It also provides guidance for the selection of fuse-links with particular reference to their time-current characteristics and ratings.

Contents include:

  • Normative references
  • Features of current limitation
  • Fuse-link time-current characteristics
  • Coordination
  • Other ratings and requirements
  • Rated voltage
  • Rated maximum breaking current
  • Rated minimum breaking current and class
  • Fuse-links used in combination or association with other switching devices
  • Fuse-links used as the only protection on the HV side of the transformer
  • Fuse-links used to provide short-circuit protection in combination with expulsion fuse-links
  • Selection of rated currents of fuse-links for transformer circuit applications
  • Comparison of operating Joule integral (I2t) for current-limiting fuses and non-current-limiting devices
  • Characteristics relating to the protection of the HV/LV transformer circuit

PD IEC/TR 60787:2007 replaces BS 6553:1984, which has been withdrawn.
