A fuzzy approach to calculate the errors due to the subdivision rate in the Maxwell’s subareas method

The more the rate of sub‐division of the grid into subareas is high, the more the Maxwell’s sub‐areas method of studying the current field generated by a grounding grid is accurate. In this paper the authors suggest a fuzzy approach applied to a horizontal cylindrical electrode which allows them to determine in advance the errors due to the different rates of subdivision.
