Aims: Paper presents the graphically observe the impact of parameters on equipotential forces. By adjusting the corresponding parameters their operation in the space can be significantly reduced. Graphics of positive and negative features equalizing line is obtained using Wolphram alpha computer program and application support functions.
Methodology: The intensity of corrosion and destruction of metal pipes is determined by the difference between the potential of soil and pipes (pipe voltage). The structure and various forms of underground pipe installations make it difficult to solve this task analytically, so that it becomes virtually impossible. Therefore, the first step in solving the task is defining a theoretical model fordetermining the value of electrical potential on the elements of underground installations. Further proceedings can determine the order and the minimum number of elements of cathode protection by which the voltage at the isolation layer of pipe is limited to allowed values.
Conclusion: To ensure the potential change along the axis of the tube, the metal surface should be divided into smaller elements of the same length, and to each element of length △l the longitudinal resistance and conductivity should be added.
