Transient processes on the elements of installation with electric conductive material may endanger the environment in urban areas and therefore action must be taken to mitigate possible consequences and protect the environment. Installation layers of lines of underground installation (electrical, gas, water…) that are used for the flow of energy/fluids do not provide a full protection and currents of static discharge discharged into the soil are particularly dangerous. At static discharges conductors receive high potentials and a strong electric field is created around them, which will be greater as the conductivity of the soil is weaker.

If the value of the field is greater than the disruptive voltage of the soil around earth wire (probe) the breakthrough occurs and the majority of soil becomes conductive. Particular problem are components of high frequency currents or voltages. Disorders of frequency in the range of 50 Hz to 5 kHz that can affect the selection of installation parameters, in compliance with all environmental criteria, are simulated by adapted subprogram in the part of the package Sym Power MATLAB.
