Specific test requirements for qualifying electrical resistance trace heating for commercial service are provided in this standard. A basis for electrical and thermal design is included, heating device characteristics are…
This standard establishes specifications for high-voltage (above 1000 V) distribution and power class expulsion, current-limiting, and combination-type external capacitor fuses and accessories, with rated voltages from 1 kV through 38…
Revision of IEEE Std C37.91-2000. This guide is intended to provide protection engineers and other readers with guidelines for protecting three-phase power transformers of more than 5 MVA rated capacity…
Superseded by C62.59-2019. Avalanche breakdown diodes used for surge protection in systems with voltages equal to or less than 1000 V rms or 1200 V dc are discussed in this…
Methods, techniques, and designs to mitigate bird-related power interruptions and equipment damage resulting from avian interactions with electric facilities are covered in this document. This document addresses electrocutions, collisions, nesting…
A uniform method is established for determining the temperature classification for the insulation systems for open-wound, solid-cast and resin-encapsulated power and distribution transformers by testing rather than by chemical composition.…
Small power transformers have become a significant element in distribution systems supplying large commercial customers like major resort hotels and site-specific industrial customers that desire the local utility to own,…
This guide presents information on establishing an effective safety program to assure compliance with the applicable regulations for radio frequency (RF) protection of electrical workers in the vicinity of wireless…
