Abstract
The objective of the present study is to propose a practical laboratory method to simulate wet atmospheric ice accretion on H.V. insulators. The method developed is based on first accumulating a low density soft rime on energized insulators and then to heat the produced deposits. The liquid water fraction of the ice accretion is then determined using a centrifuge. This approach makes it possible to determine the performance of insulators under wet-snow-like conditions with relatively simple, low cost equipment
