Estimating Insulator Contamination from Site Meteorological Parameters by Massimo Marzinotto

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.
