Abstract
Liquid cooling type gas-insulated transformer utilizes perfuruorocarbon (C8F16O) and SF6.If the faults in transformer occur, insulating materials generally are decomposed by overheat, Recently, we found that the decomposed products from each insulating materials slightly dissolved in perfuruorocarbon.
Analysis of decomposed products in perfuruorocarbon offers a new diagnostic technique for liquid cooling type gas-insulated transformer.Decomposed products characteristics to each insulating materials were identified by the decomposed experiments.
Decomposed products dissolved in perfuruorocarbon were analyzed by high-performance liquid chromato -graphy with ultraviolet detector.
