PC37.41 - Standard for Design Tests and Specifications for High-Voltage (> 1000 V) Fuses and Accessories
This standard establishes design tests and specifications for high-voltage (above 1000 V) fuses and accessories for use on alternating current (ac) electrical distribution systems. Devices with rated maximum voltages to 170 kV are covered. The devices to which this standard applies are as follows: a) Expulsion fuses (including fuse cutouts); b) Current-limiting fuses; c) Items a) and b) used in fuse-enclosure packages; d) Fuse supports of the type intended for use with fuses and fuse disconnecting switches; e) Disconnecting devices (fuse disconnecting switches, disconnecting switches, and disconnecting cutouts) created by the use of a removable fuse unit or switch blade in a fuse support; f) Expulsion, current-limiting, and combination types of external capacitor fuses used with a capacitor unit, a group of units, or capacitor banks; g) Backup current-limiting fuses ("motor-starter fuses") used in conjunction with high-voltage motor starters; h) Fuse links when used exclusively with expulsion fuses and fuse disconnecting switches; i) Items a) through f) having integral load-break means; j) accessories including mounting brackets and switch sticks (switch hooks). This standard may also be used as a basis for testing other devices that are similar to the devices listed in the scope. In addition, the parts relating to expulsion fuses may, where applicable, be used for non-expulsion fuses in which the interruption process waits for a natural current zero to clear the circuit.
C37.41-2008 - IEEE 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
Required procedures for performing design tests for high-voltage distribution class and power class fuses, as well as for fuse-disconnecting switches and enclosed single-pole air switches, are specified. These design tests, as appropriate to a particular device, include the following test types: dielectric, interrupting, load-break, radio-influence, short-time current, temperature rise, time-current, manual operation, thermal-cycle, bolt torque, and liquid tightness.
Revision of IEEE C37.41-2008 and supersedes IEEE C37.40-2003. Required procedures for performing design tests for high-voltage fuses, as well as for fuse disconnecting switches, are specified. These design tests, as appropriate to a particular device, include the following test types: dielectric, interrupting, radio-influence, temperature-rise, time-current, manual-operation, liquid-tightness, thermal-cycle, bolt-torque, withstand tests for motor circuit fuses, expulsion fuses using polymeric insulators, load-break, and short-time current.
