Biography

Estimating Insulator Contamination from Site Meteorological Parameters

Dr. Marzinotto received his Masters and PhD in electrical engineering at La Sapienza University in Rome, after which he joined the Electrical Engineering Department for several years. Since 2008 he has been with the Engineering Department of Italian TSO, Terna, with main interests in high voltage polymeric materials, power cables, insulators, applied statistics, insulation coordination and transients. He is a member of IEEE-DEIS, IEEE-PES, EPRI, CIGRE and the Italian Electrotechnical Committee and is active in different IEEE Committees and CIGRE WGs. He is author of international publications on IEEE transactions and conferences as well as co-author of Extruded Cables for High Voltage Direct Current Transmission: Advances in Research & Development.

Quantifying contamination is paramount for correct insulation coordination but is difficult since it depends on insulator type and the environment where it is installed. Insulator shape, material and orientation all play a role in pollution deposition as well as impact of natural cleaning by rain and wind. This presentation reviews different models of contamination from sea aerosols and dust generation among others and presents specialized software that implements these models within a statistical framework to manage uncertainties affecting this multi-variant problem. Simulation results are compared with field measurements from three sites in Italy.
