The methodology described in Relevant Characteristics of HV and EHV Lines enables solving several types of problems in electric-power delivery that were considered for a long time in professional and scientific circles as unsolvable. Taking into account the influence of all surrounding metal installations on the relevant characteristics of HV and EHV lines passing through urban and/or suburban areas, this reference provides safe and economical solutions to the following practical problems: - Checking and achieving the prescribed safety conditions inside and in the vicinity of the supplied substations, - Determination of the dangerous and harmful inductive influence of HV and EHV lines on any of the surrounding metal installations, in normal operating conditions or faulty conditions, and - Determination of actual transfer capacities (serial impedances) of HV and EHV distribution lines.

The application elements in the chapters enable compensation of deficiency of all unknown, but relevant data concerning the surrounding metal installations in solving each of the mentioned problems. This book is necessary for properly dimensioning cable systems considering the existing underground structures near substations and provides engineers with the necessary information to design normal cable operations and determine fault events.
