Practical Methods for Analysis and Design of HV Installation Grounding Systems by Ljubivoje M. Popovic Practical Methods for Analysis and Design of HV Installation Grounding Systems gives readers a basic understanding of the modeling characteristics of the major components of a complex grounding system. One by one, the author develops and analyzes each component as a standalone element, but then puts them together, considering their mutual disposition, or so-called proximity effect. This is the first book to enable the making and analysis of the most complex grounding systems that are typical for HV substations located in urban areas that uses relatively simple mathematical operations instead of modern computers. Since the presented methods enable problem-solving for more complex issues than the ones solved using National, IEC and/or IEEE standards, this book can be considered as an appendix to these standards. Develops general equations of lumped parameter ladder circuits Includes the analytical expression for determination of ground fault current distribution for a fault anywhere along a cable line Presents measurement and analytical methods for the determination of actual ground fault current distribution for high-voltage substations located in urban areas Provides the analytical procedure for the determination of the critical ground fault position for faults appearing in outgoing transmission lines Defines testing procedure for the correct evaluation of grounding systems of substations located in urban areas

Overhead power line - Wikipedia
Sometimes all conductors are installed with the erection of the pylons; often some circuits are installed later. A disadvantage of double circuit transmission lines is that maintenance can be difficult, as either work in close proximity of high voltage or switch-off of two circuits is required. In case of failure, both systems can be
