1. Evaluating Resistance to Corona and Ozone in Polymeric Materials for High Voltage Outdoor Applications
Sammanfattning : Resistance to corona discharges and ozone, the well known ageing factors for polymeric materials used in outdoor insulation, has been listed as being of great importance among twelve properties identified by CIGRE WG D1.14 – Material Properties for Non-ceramic Outdoor Insulation. LÄS MER
2. Effects of Corona and Ozone Exposure on Properties of Polymeric Materials for High Voltage Outdoor Applications
Sammanfattning : 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. LÄS MER
3. Condensation and frost formation in fibrous thermal-insulation materials
Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER
4. Image Analysis for Diagnostics of Insulators with Biological Contamination
Sammanfattning : Composite insulators have a number of advantages compared to conventional insulators. However, 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 performance of the materials. LÄS MER
5. Solar Thermal Collectors at High Latitudes : Design and performance of non-tracking concentrators
Sammanfattning : Solar thermal collectors at high latitudes have been studied, with emphasis on concentrating collectors. A novel design of concentrating collector, the Maximum Reflector Collector (MaReCo), especially designed for high latitudes, has been investigated optically and thermally. LÄS MER
