UNDERGROUND CABLE MAGNETIC-FIELD SIMULATION AND MANAGEMENT USING NEW DESIGN CONFIGURATIONS

This paper addresses one of the most important sources of magnetic fie lds: underground power cables. New design configurations for one, two, three and four cables per phase are presented from a magnetic field p erspective. Different management techniques are studied in detail. Jud icious placement of cable phases in multiconductor lines to reduce the field effect is implemented by computer modeling and simulations. The state-of-the-art magnetic field simulation package PCFIELD developed by EPRI is used to quantify and present the tool used to manage the fi eld values. The new design configuration cases are very useful from a magnetic field point of view and have low cost schemes that can be eas ily implemented. (C) 1998 Elsevier Science S.A. All rights reserved.
