This paper describes a new testing procedure developed by TERNA (the Italian TSO) for RTV insulators and composite insulators sampled from field. The procedure is based on proper flashover voltage tests, followed by hydrophobicity-recovery tests, and is unique for both RTV and composite insulators. The paper also describes the statistical processing results for a few insulators removed from TERNA's HV and EHV overhead lines after some years' service and tested in an external research laboratory following the proposed procedure.

Abstract
This paper describes a new testing procedure developed by TERNA (the Italian TSO) for RTV insulators and composite insulators sampled from field. The procedure is based on proper flashover voltage tests, followed by hydrophobicity-recovery tests, and is unique for both RTV and composite insulators. The paper also describes the statistical processing results for a few insulators removed from TERNA's HV and EHV overhead lines after some years' service and tested in an external research laboratory following the proposed procedure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
