Biography

1. Pollution Design & Testing: Unresolved Issues
2. RTV Coatings on Ceramic Insulators: Latest Developments and R&D Needs

Dr. Pigini received a Doctoral Degree in Electrical Engineering from the University of Milan. He worked for more than 35 years at CESI, first as a researcher, then as Research Manager and finally as Division Director, responsible for a number of aspects of HV electrical system, including environmental impact and generation. He is a Distinguished Member of CIGRE, Fellow of IEEE and active in various WG and Committees at these bodies. Recipient of the 2015 Claude de Tourreil Memorial Award for Lifetime Achievement in the Field of Electrical Insulators, he acts as consultant to international clients and has also served as expert Contributor to INMR for more than 10 years.

1. 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.

2. The past decades have seen development of a variety of surface engineering techniques and advanced coatings with hydrophobic, self-cleaning, icephobic and anti-corrosion properties. These advances benefit the power industry by reducing risk of insulator flashover due to pollution and icing, corona noise from conductors, fittings and insulators, corrosion of metal components and mechanical problems caused by ice and snow accretion on overhead lines. This presentation deals with RTV coatings applied to outdoor insulation and summarizes key aspects of the information collected in CIGRE WG B2.69, 2021 Brochure while also underlining unresolved issues that deserve additional investigation.
