IEEE C37.48-1997

These guidelines apply to the following specific types of equipment: a) Distribution and power class expulsion type fuses; b) Distribution and power class current-limiting type fuses; c) Distribution and power class fuse disconnecting switches; d) Items a) through c) used in fuse-enclosure packages (see types listed in 1.2 and 1.3); e) Fuse supports, fuse mountings, and fuse hooks, of the type intended for use with distribution and power class fuses, and fuse disconnecting switches; f) Removable switch blades of the type used exclusively with distribution class oil cutouts, power class fuses, and distribution class fuse disconnecting switches; g) Fuse links of the type used exclusively with distribution class oil cutouts, power class fuses, and distribution class fuse disconnecting switches; h) Distribution class oil cutouts; i) Distribution class enclosed single-pole air switches; and j) Distribution and power classes of expulsion, current-limiting and combination external capacitor fuses used with a capacitor unit, groups of units, or capacitor banks. To bring the document up to date. Revision Standard - Superseded. Information on the application, operation and maintenance of high-voltage fuses (above 1000 V), distribution enclosed single-pole air switches, fuse disconnecting switches, and accessories for use on ac distribution systems is provided. This guide is one of a series of complementary standards covering various types of high-voltage fuses and switches, so arranged that two of the standards apply to all devices while each of the other standards provide additional specifications for a particular device. For each device, IEEE Std C37.40-1993, IEEE Std C37.41- 1994, plus the standard covering that device, constitute a complete set of standards for each device. In addition, IEEE Std C37.48-1997 is an application, operation, and maintenance guide for all the devices.
