The problem of identification and separation of two Partial Discharge (PD) phenomena simultaneously active has been investigated. Combined PD phenomena, caused by different PD mechanisms, are separated by means of a stochastic procedure based on the mixed Weibull function applied to pulse height distributions. The results are compared with those derived from PD measurements performed on the electrode configurations that produce a single PD mechanism at a time. It is shown that inference of Weibull function parameters can be useful for PD phenomena identification.

Abstract
The problem of identification and separation of two Partial Discharge (PD) phenomena simultaneously active has been investigated. Combined PD phenomena, caused by different PD mechanisms, are separated by means of a stochastic procedure based on the mixed Weibull function applied to pulse height distributions. The results are compared with those derived from PD measurements performed on the electrode configurations that produce a single PD mechanism at a time. It is shown that inference of Weibull function parameters can be useful for PD phenomena identification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
