Development of an Algorithm and Software “MVES-TV 2012” for Touch Voltage Evaluation in MV Networks

Abstract

The paper presents an algorithm for evaluation of touch voltage in medium voltage networks with different types of neutral earthing. The proposed algorithm takes into account power line type (overhead line, underground cable line), earth fault value, number of substations, etc. Based on this algorithm, new software “MVES-TV 2012” (Medium Voltage Electrical System Touch Voltage) is developed by the authors of this paper. Evaluation with this software ensures the safety of human life in any switchgear place to which persons have legitimate accesses. This software can be useful for distribution network project and exploiting engineers when trying to evaluate touch voltage in medium voltage networks
