Internal PD Pulses Analysis Accompanying with Bush-type Tree in Solid Dielectrics
고체유전체에서 발생한 부시형 전기트리에 수반된 내부 부분방전 펄스 해석
Abstract
Correlation between propagation of bush-type electrical tree and internal partial discharges(PD) was discussed. We used specimens with needle-plane electrode system made of LDPE(Low Density Polyethylene), observed inception and propagation of electrical tree by optical microscope interfaced with computer and investigated characteristics of phase resolved PD pulses accompanying with propagation of electrical tree. Electrical tree generally growed bush-type tree. PD data detected and analyzed were average discharge current and statistical operator of q-n,
