An improved materials system for maintaining high resistivity of electrical insulation in humid environments

One of the environments which has long been considered hostile to electrical insulation is that of elevated humidity. In this environment, severe degradation of insulation resistance is among the significant effects on electrical insulating materials. This paper discusses the background and nature of the problem of decreasing insulation resistance of electrical insulation in humid environments, and presents an approach for maintaining high insulation resistance during exposure to such humid environments.
