In India, the implementation of Gas Insulated Substation (GIS) has been accelerated for two decades. In the case of GIS, the electric and magnetic field estimation is very important because of the shorter distances of bus bars and line sections. Several others have given the estimation of electric and magnetic fields by solving nonlinear differential equations using numerical techniques. In this paper, the advanced simulation tools ELECNET and MAGNET have been used to estimate these fields. A typical 245k V GIS is considered for Modeling and simulation. The four important locations, XLPE cable termination, gas-to-air bushing, bus link, and current transformer (CT) position, have been considered. The resultant fields were obtained. These values are compared with Electric and Magnetic field measurements at the same substation. For these measurements, a Gauss meter and an E-field meter were used. These meters are calibrated per IEEE 644-1994 and IEEE 644-2019. The measured values are in good agreement with the simulation results. Hence, the triangular grid model and Modeling are dependable for further simulations. The results show that the bus link and CT position fields are higher than those of other locations.
