IEEE 1137 CORR 1

Abstract

Foreword&#160;<br>IEEE Std 1137-1991 provides guidance for controlling or modifying the inductive environment and the susceptibility of affected wire line telecommunications facilities in order to operate within the acceptable levels of steady-state or surge induced voltages of the environmental interface (probe wire) defined by IEEE Std 776-1987. Procedures for determining the source of the problem are given. Mitigation theory and philosophy are discussed, and mitigation devices are described. The application of typical mitigation apparatus are addressed. Advice for determining the best engineering solution is offered, and general safety considerations are discussed.<br>This document was suggested during the preparation of IEEE Std 776-1987 as a companion in the area of implementing mitigating techniques. The following individuals made a significant contribution to the effort.<br>David Boneau<br>Chrys Chrysanthou<br>Russ Gundrum<br>Harold Held<br>Ron Jones<br>Bill McCoy<br>Charlie Nelson<br>Dick Nelson<br>Stan Overby<br>Keith Sabine<br>This guide was prepared by the working group on Longitudinal Induction of the Transmission Systems Committee of the Communications Society.

Engelman<br>Stanley Warshaw<br>Deborah Czyz<br><em>IEEE Standards Project Editor </em><br>Scope<br>This Guide offers users assistance in controlling or modifying the inductive environment and the susceptibility of affected wire-line telecommunications facilities in order to operate within the acceptable levels of steady-state or surge-induced voltages of the environmental interface (probe wire) defined by IEEE Std 776-1987 [4]¹. The methodology, application, and evaluation of results for mitigative techniques or devices in general are addressed for all Specific Type A and Specific Type B coordination methods also defined by IEEE Std 776-1987 [4].
