Abstract: This content has been transferred from the main text, since today's predominant bushing technology does not suffer from flashover during conditions of uneven wetting, in comparison to the earlier used ceramic insulators. Today's outdoor bushings in HVDC applications are made with composite insulators with silicon sheds with well proven hydrophobicity. Furthermore, there exist no verified test method with sufficient reproducibility between different laboratories. It is also difficult for operators to have full knowledge or clear data on how to arrange a test setup that reflects actual site conditions. Subsequently, uneven wetting test is not relevant for composite insulators. The testing may still be performed to outdoor bushings, particularly with ceramic insulators, but shall be agreed between purchaser and manufacturer.
