Analysis of Partial Discharge Using Non-Linear Clustering Algorism

In this paper, we examine discharge characteristics of cross-linked polyethylene (since then; XLPE) according to void. Voltage was applied to power frequency by step method, and calibration of discharge was set to 50[pC] (slope=8.333). After the voltage was applied, for 10 [sec] (600 [cycle]), occurring discharge and number were detected. Determine of input pattern is difficult because discharge pattern is irregular. Therefore we investigated phi-q-n pattern using the clustering method, and investigated variation of center vector and cluster member
