This technical report provides information for understanding the construction, operation and application of high-voltage fuses in general. Current-limiting, expulsion, electronic, and other, non-current-limiting, fuses rated above 1 kV a.c. are all covered, as are North American, European and other application practices. As a technical report, this document contains no requirement and is informative only.
