Influence of Different Pollution Sources on Performance of Insulation: Back to Basics

Assessing pollution level must be done whenever a new grid is defined or operating voltage is modified. Choice and dimensioning of insulation is closely linked to contamination exposure of equipment while criticality of surface pollution depends on both its quantity and its nature. Inappropriate insulation selection can lead to problems such as increased cost of structures due to over-dimensioning or the need to upgrade structures in the case of under-dimensioning. This presentation deals with characterization of pollution level using classical tools and aims to demonstrate that pollution modelling is complex and requires in-depth expertise. It also highlights limitations of each alternative method as well as associated level of confidence.
