2. Effects of Corona and Ozone Exposure on Properties of Polymeric Materials for High Voltage Outdoor Applications
Abstract : Despite the past four decades of service experiences with polymeric insulators in power systems all over the world, an adequate standard allowing for proper selection of polymeric materials for applications in high voltage outdoor environments has still been lacking. Therefore CIGRE Working Group D1. READ MORE

5. Diagnostic Methods for Composite Insulators with Biological Growth
Abstract : Composite insulators have a number of advantages compared to conventional insulators, but the fact that they are more prone to aging is a major drawback. For instance, biological growths, like algae and fungi, have been found to colonize composite insulators, and possibly effecting the insulation performance. READ MORE
