Analysis of Partial Discharge Signal Propagation Characteristics in GIS Using FEM/EMTP
FEM/EMTP를 이용한 GIS내 부분방전 펄스의 감쇠특성 해석
Abstract
This paper was studied electromagnetic field distribution and damping of PD(Partial Discharge) signal in GIS(Gas Insulated Switchgear). Cut-off frequency of electromagnetic wave propagation modes were computed, electromagnetic field distribution of propagation modes in GIS by FEM(Finite Element Method) were simulated and simulated damping characteristic of electromagnetic waves in GIS by EMTP(Electromagnetic Transient Program) when generated PD pulse. Frequency band of
