Sensitivity Analysis of Earthing System Impedance for Single and Multilayered Soil
Original language description
Over the last decades computer power has grown and it is now possible to use computers for solving any electromagnetic problem by the approach of solving rigorous electromagnetic field (EMF) equations (Maxwell´s equations). With the use of this technique, it is possible to easily model an earthing system (ES) with a uniform or non-uniform soil model. This paper thus points out to the possible error between the analytical and EMF approach when determining ES resistance that has a crucial effect on resulting human safety. Three different ESs of distribution system substation were modelled using EMF simulation software (Ansoft Maxwell) for uniform and two layer soil models. The expected earthing resistances were determined for the ES models and compared with the values obtained by an analytical uniform soil model. The calculation was done for two different values of surface soil resistivities as well as for four different values of the surface layer thickness. Both values were compared which indicated the possible error that is being made when using an old analytical approach.
