Abstract
In this paper is proposed new method for analysis the main characteristics of a grounding elements, and, furthermore, characteristics of some types of grounding elements of towers of overhead lines, mostly used in middle voltage (MV) power networks are calculated and presented in a different, new way. Main characteristics of each grounding element are set of properties, forming some kind of identity card for those grounding elements, unique and easy for recognizing their characteristics. The set of informations, forming this identity card, are resistivity to ground R, potential distribution on the earth surface in the vicinity of the grounding and, as an additional data describing the characteristics of the grounding that can be used further for analysis the safety conditions and risks of hazard shock, the probability density functions (PDF) of the touch and step potentials (ie potential differences s t E, E∆∆), and finally, risk level of accident (death) due to appearence of dangerous potentials. While calculation the PDF-s and risk level from dangerous step and touch potential differences occuring during the fault arround the transmission towers on which human body might be exposed, using stochastic (Monte Carlo) simulation are calculated number of experiments, produced and analysed by the computer. In each experiment, using random numbers generated from the computer, human body impedance, current of fibrillation threshold and probability of fatal accident, as random variables are calculated.
