IEEE C37.48.1-2002

A user survey indicated considerable misunderstanding on the different types of high voltage current limiting fuses in regard to their operation, classification, application, and coordination. Hence, the guide will deal with these issues in a tutorial fashion and provide a much needed enhancement to the existing C37.48 document. There is currently no technical document which explains to the user or specifier the basic differences between various types of current limiting fuses, how they work, applicational rules and guidelines, and how to apply or coordinate them with other system elements. This project will provide an addition to C37.48 and give a clear understanding to the user regarding function, selection, and application of these devices. New IEEE Standard - Superseded. Additional guidelines for application and coordination of high-voltage power- and distri-bution-class current-limiting fuses are provided.
