Status of Pollution Test Procedures for Insulators Made from Hydrophobicity Transfer Materials

While pollution tests are specified in the standards for ceramic insulators for AC and DC applications, insulators made with hydrophobicity transfer materials are not in the scope of these standards. IEC 60815-3, for dimensioning composite insulators in polluted conditions, states only that in the absence of recommended tests, these can be agreed between the user and manufacturer. This presentation updates the state-of-the-art of pollution testing of HTM insulators in different parts of the world.
