Based on various statistical parameters extracted from partial discharge
in the contribution
by introducing the financial time sequence analyzing method
a novel parameter indicating the development trend of partial discharge
namely partial discharge-volume-trend
is proposed.PVT can display and discover the abnormal case in the partial discharge developing process more clearly in comparison to other parameters of PD.For validating the performance of PVT
two practical applications are analyzed.Results obtained demonstrate that PVT can provide promising support for the evaluation of partial discharge.
