Analysis of the Electric field of the 1200kv power transmission line using the Finite Element Method

Effects of parameter adjustment on the electromagnetic field of an overhead power transmission line model

“…Figure 3(b) shows the simulation results of Arora and Deshpande [27]. The electric field intensity is 8.7 kV/m at y = 0 m and the electric field intensity is 12.5 kV/m at y = 10 m. The trend is similar to that for the simulation results in this study, where the electric field intensity increases with an increase in height above the ground.…”

“…The electric field intensity is 8.7 kV/m at y = 0 m and the electric field intensity is 12.5 kV/m at y = 10 m. The trend is similar to that for the simulation results in this study, where the electric field intensity increases with an increase in height above the ground. The simulation results in this study are similar to those of Arora and Deshpande [27], with only a small difference in magnitude, which is probably due to the difference in the version of COMSOL multiphysics software and limitation of data. Owing to the small difference in magnitude of the simulation results, the overhead power transmission line model is validated.…”

“…In Phase 1, two-dimensional overhead power transmission line models were developed using COMSOL Multiphysics Version 6.0 software in order to determine the electric and magnetic field distributions at human heights. The overhead power transmission line models were validated by comparing the simulation results with those of Arora and Deshpande [27] and Rachedi et al [28]. In Phase 2, the parameters (voltage of the conductors, current carried by the conductors, conductor radius, and horizontal spacing between the phase conductors) were adjusted to investigate their effects on the electric and magnetic field distributions of the overhead power transmission line model.…”

“…To determine the electric field distribution, the model was developed based on the work of Arora and Deshpande [27], which is a 1200-kV overhead power transmission line model with D/C vertical configuration, as shown in Figure 2(a). Each phase consists of two cables and the conductor radius is 0.518 m. The distance from the ground to the lowest conductor is 24.3 m while the vertical distance between the phase conductors is 26 m. To determine the magnetic field distribution, the overhead power transmission line model was developed based on the work of Rachedi et al [28].…”
