A method to determine electric field in thesurroundings of warning lights for three-phase power lines ofhigh voltage, utilizing finite element method (FEM), is presentedin this paper. This work is a preliminary stage in the designprocess of these devices, in order to define optimum geometrybefore manufacturing and laboratory test. The results of thisresearch show that electric field is lower when they are used inpower line with more than one conductor per phase (bundle ofconductors). Laboratory-test results demonstrate the effectivenessof the proposed method to determine electric field distributionand corona inception voltage.
