This guide provides information for understanding the construction, operation, and application of highvoltage (> 1000 V) fuses and accessories, intended for use on alternating current (ac) electrical distribution systems. Current-limiting, expulsion, electronic, and other non-current-limiting fuses and accessories are covered, as are North American, European, and other application practices. As a guide, this document contains no requirements and is informative only. The purpose of this guide is: a) To help prospective users and protection engineers understand the basics of high-voltage (> 1000 V ac) fuse technology and applications involving high-voltage (HV) fuses b) To illustrate the particular and unique advantages of fuse protection for most service applications c) To reduce possible misapplications of fuses which could lead to problems in the field d) To list and describe the many types of fuse in use today, and the international standards that apply to them, including fuse types not specifically included in IEC, IEEE, or other recognized standards This guide gathers information previously published in IEC, IEEE, and other publications, as well as new material.
