In power system, pulse voltage is measured by both the circuit and the electric field. The special measure of VFTO is determined by non-alterable equipments of GIS. In this paper, external transient voltage is measured by electric spherical probe which means it is not necessary to access any equipment to the system. According to actual space between three phase external lead wire in GIS, we built...

The electromagnetic environment of the High Voltage Direct Current (HVDC) is much more complex than ever, main protection plus backup protection with tradition meaning are limited. The EMC of the PCB in the secondary equipments is top priority. In this paper Finite Integration Theory (FIT) method was applied to the analysis the resisting EMI of the PCB in high frequency. The model bases of the real...
