BS PD IEC/TS 62073:2016

The methods described in BS PD IEC/TS 62073:2016 can be used for the measurement of thehydrophobicity of the shed and housing material of composite insulators for overhead lines,substations and equipment or ceramic insulators covered or not covered by a coating. Theobtained value represents the hydrophobicity at the time of the measurement.The object of this technical specification is to describe three methods that can be used todetermine the hydrophobicity of insulators. The determination of the ability of water to wet thesurface of insulators may be useful to evaluate the condition of the surface of insulators inservice, or as part of the insulator testing in the laboratory.
