Standard Design Tests for High-Voltage (>1000 V) Fuses@ Fuse and Disconnecting Cutouts@ Distribution Enclosed Single-Pole Air Switches@ Fuse Disconnecting Switches@ and Fuse Links and Accessories Used with These Devices
This standard specifies design test requirements for high-voltage (above 1000 V) fuses@ distribution enclosed single-pole air switches@ fuse disconnecting switches@ and accessories for use on alternating-current distribution systems. The devices to which this standard applies are as follows:a) Distribution and power class expulsion type fusesb) Distribution and power class current-limiting type fusesc) Distribution and power class fuse disconnecting switchesd) Item a) through item 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 switchesf) Removable switch blades of the type used exclusively with distribution class oil cutouts@ power class fuses@ and distribution class fuse disconnecting switchesg) Fuse links when used exclusively with distribution class oil cutouts@ power class fuses@ and distribution class fuse disconnecting switchesh) Distribution class oil cutoutsi) Distribution class enclosed single-pole air switchesj) Distribution and power classes of expulsion@ current-limiting@ and combination external capacitor type fuses used with a capacitor unit@ groups of units@ or capacitor banks.The distribution and power class expulsion type fuses listed previously in item a) through item j) are the same as those covered in IEC 60282-2 (1995-09)1. The distribution class expulsion type fuses are the same as the IEC 60282-2 class ??A?? fuses@ and the power class fuses are the same as the IEC 60282-2 class ??B?? fuses. At present@ IEEE standards do not cover the class ??C?? fuses listed in IEC 60282-2 (1995-09). Some of the current-limiting type fuses listed above are the same as those covered in IEC 60282-1 (1994-12). IEEE Std C37.41-2000 contains specific requirements for more types of current-limiting fuses than are covered in IEC 60282-1 (1994-12). Use caution if devices specified and tested per ANSI/IEEE standards are compared to those specified and tested per IEC standards@ as they may or may not be the same.
