From Service Experience to Improved Standards: Lessons from a Decade of After-Service Testing of Composite Insulators (in English)

Johan Lundengård is a high-voltage engineering expert at Independent Insulation Group (I2G), Sweden, with more than 30 years of experience in high-voltage technology and electrical insulation. Previously, he worked for many years at STRI, specializing in high-voltage testing. He holds a B.Sc. in Electrical Engineering from Mälardalen University. His expertise includes high-voltage testing, insulation dimensioning, condition assessment, and failure investigations of glass, porcelain, and composite insulators. In recent years, his work has focused particularly on after-service testing of composite insulators, investigating ageing, material properties, and failure mechanisms, as well as developing improved testing and diagnostic methods. He has co-authored numerous technical publications and is a member of the Swedish National Committee for IEC TC 36 (Insulators).
