초록

The Acoustic Emission due to treeing progress in Crosslinked Polyethylene(XLPE) is studied by using the self developed automatic measuring system of acoustic emission. Tree progression and average pulse amplitude are almost in proportion to the rising of applied voltage but there is no proportionality relation between tree progression and pulse numbers. From now on, Skewness and kurtosis of average cycle, special property of $\phi$-a distribution characteristics can be confirmed as the useful parameters of treeing deterioration.
