Information on the concepts of protection of ac transmission 1ines is presented in this guide. Applications of the concepts to accepted transmission line protection schemes are presented as well. Many important issues, such as coordination of settings, operating times, characteristics of relays, mut...

A procedure to be used to perform a failure analysis is recommended. The procedure is primarily focused on power transformers used on electric utility systems, although it may be used for an investigation into any ac transformer failure. This document provides a methodology by which the most probabl...

Metal-clad (MC) medium-voltage switchgear that contains drawout electrically operated circuit breakers is covered. MC switchgear is compartmentalized to isolate components such as instrumentation, main bus, and both incoming and outgoing connections with grounded metal barriers. Rated maximum voltag...

This revision specifies technical corrections and clarifications to IEEE 802.11-1999 as reaffirmed in 2003 for wireless local area networks (WLANS) as well as enhancements to the existing MAC and PHY functions.

This standard establishes a model for the implementation of the ECG Virtual Medical Device. It establishes a Design Model and specifies how this Model should be implemented. It also provides guidance concerning bandwidth requirements as well as how to specify conformance with this standard.
