Analysis of Performance Test of Low-Loss Pole Transformers for distribution Line

In order to obtain the useful data for quality control of the pole transformer and supply the stable electric power in distribution line, The evaluation of performance for low-loss pole transformer had been performed for new products and ones under operation for several years in distribution line. As the results, we found that the rate of fail were very high in gaskette, short-circuit strength and temperature-rise test, especially 48 percent in gaskette test.
