Biography

Designing & Testing Solid-Core Bushings for Pollution & Long Service Life

Mr. Pastore received his Mechanical Engineering Master’s Degree from the University of Naples Federico II. After graduation, he began his career in R&D and technology in the automotive and railway sectors. In 2012, he joined the power grid business working for Alstom Grid as R&D Mechanical Engineer for product industrialization of through-wall & transformer bushings with special focus on HVDC applications. Since 2015, he has been at GE Grid Solution covering different roles in engineering manufacturing, production and technical manager for high voltage bushings and relevant technologies.

Bushings play a major influence in reliability of transformers and require good thermal dissipation behavior, reliable internal and external electrical insulation and adequate mechanical strength. The main technologies for internal insulation are oil-impregnated paper (OIP), resin-impregnated paper (RIP), resin-impregnated synthetic (RIS) and SF6, each offering relative advantages and disadvantages. All technologies are characterized by very high reliability based on service and manufacturing experience. This presentation discusses the findings of recent R&D work aimed at demonstrating suitable design criteria to ensure long service life of dry RIP bushings, where growing market demand relates to their safety aspects.
