摘要：
Environment friendly and non-hazardous behavior of natural ester has gained significant attention as a potential substitute for conventionally used mineral oil over the past decade. Such a substitute for mineral oil should be compatible with the paper insulation since the quality of paper is the life determining aspect of the transformer. Here an attempt is made to check the compatibility of paper insulation with soyabean based natural ester by comparing the dielectric properties and thermal stability of natural ester impregnated paper with mineral oil impregnated paper. Impregnated Paper was subjected to accelerated thermal aging at 130 degree Celsius for 7 days and the degree of polymerization was investigated. Experimental results show that the degradation is lesser for the natural ester impregnated paper, which further guarantees the compatibility of paper insulation with natural ester.
