This book examines the role of the geotechnical baseline report (GBR) as a means of allocating and managing subsurface risks associated with subsurface construction.

This newly developed guide compiles information on the application considerations of protective relays to ac transmission lines. The guide describes accepted transmission line protection schemes and the different electrical system parameters and situations that affect their application. Its purpose is to provide a reference for the selection of relay schemes and to assist less experienced protective relaying engineers in their application.

Abstract: General recommendations for the in-service care, maintenance, and testing of the conductive clothing worn by workers to perform work in high-voltage fields are presented. Keywords: clothing, conductivity, energized, IEEE 1067, maintenance, power lines.
