Silicon Insulating Rubber and Thermoplastic Elastomeric Materials have replaced old ceramic insulators since last three decades and are being used all over the world now-a-days. Moreover they are used very extensively as outdoor electrical Insulation. These materials being partially organic age / degrade due to environmental effects e.g. UVR, Temperature, Humidity and Rain etc, so their performance check is very essential before use in any environment. Accelerated Multistress aging technique is the best one at the moment. This paper describes this technique in detail. The results of many such analysis performed in world has been summarized and useful conclusions drawn along with the future needs of research. |
