Pollution Design & Testing: Unresolved Issues by Alberto Pigini

Assessing pollution severity has been the subject of many past CIGRE studies but recently has received less attention with the disbanding of Study Committee 33 ‘Insulation Coordination’. Revision of the latest IEC Technical Specification 60815 is now underway given realization that certain aspects of insulation design for polluted service environments are still not sufficiently clarified. Setting up a new WG comprised of experts in the field is therefore urgent, especially given the importance of pollution assessment in insulation design of DC systems. This presentation reviews areas that could benefit from additional CIGRE support.
