Formulas for Calculating Physical Grounding Resistance of Grounding Wire - Electric Pole System of High Voltage Transmission Lines

Abstract

The calculation of physical grounding resistance of grounding wire and electric pole system is always interested by the designer of transmission line, high voltage substation. This grounding system shall contribute to reduce the value of safety grounding resistance of high voltage substation. The paper studied and suggested some formulas for calculation of physical grounding resistance of grounding wire and electric pole system with more precise than announced materials.
