The proven reliability of ceramic cap-and-pin insulators for high voltage (HV) and extra-high voltage (EHV) overhead lines suffers in the presence of harsh industrial or strong salt pollution [1]. In these cases, apart from the countermeasures such a

The paper reviews previous work on the DC inclined plane test and suggests equivalent DC voltage levels in parallel to AC voltage in the ASTM inclined plane tracking and erosion test. The aim of this work is to provide a basis for standardizing the i
A testing procedure for RTV pre-coated glass cap-and-pin and composite insulators sampled from field
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

The paper gives the state-of-the-art on pre-coated ceramic insulators for transmission lines. The usage of pre-coated ceramic insulators has mainly been in coastal areas where sea salt causes flashovers of ceramic insulators. The experience to date h
