Guidance on the measurement of hydrophobicity of insulator surfaces Ingestion-build-83346 By adopting ISO 17677‑1-compliant vocabulary1 Scope The methods described in this technical specification can be used for the measurement of the hydrophobicity 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. The obtained 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 to
