Development of IEC-Based Methodology for Site Severity Assessment

Utilities must evaluate design pollution severity for new overhead lines and substations as well as during uprating and refurbishment projects. This is mandatory not only when pollution performance is the dominant dimensioning factor but also for less polluted environments to optimize insulation selection. This presentation discusses methods of pollution monitoring and how these are being continually improved, as confirmed by comprehensive findings. It also explains a ‘smart’ combination of different methods to achieve the best possible evaluation of site pollution severity (covering both type A and B pollution) and how such an approach allows creation of pollution maps covering entire networks.
