Davide Pinzan joined UPorto’s InnoDC team for three months, December 2018 – February 2019, where he worked alongside Prof Helder Leite, Prof António Machado e Moura, and engineer, Fábio Branco, in the University’s High Voltage laboratory. He conducted a test programme on composite insulators under switching impulse superimposed on High Direct Voltage. The experimental results led to his paper in the IEEE Transactions on Power Delivery, and a conference paper. His secondment experience strengthened the bond between Davide, Emily Maggioli and Motaz Ayiad who supported each other and shared research ideas.
