An Overview of Quality Testing of Insulating Materials and its Technical Considerations used for Different Parts of Generator

The insulating systems are the basic requirement and have wide range of applications in the fields of power generation, electrical, electronics, telecommunications. The higher trends in modern electrical technology have led to the usage of facilitated voltage power generation. This had led to increase usage of power consumption. The insulating material is the major contributing factor in the reliability of devices. The type and quality of insulation affects its cost, weight, size, performance and life. The electrical behavior and performance of Insulating materials depends and mainly influenced by certain parameters like its dielectric strength, insulation class, porosity or penetrability, ageing, tensile strength and shelf life. These quality parameters testing enhance the stability and withstanding capability of mainly an electrical generator. In this paper, we have recorded the testing of certain resin rich and resin poor insulating materials samples under above mentioned electrical and mechanical aspects of the materials.
