Zusammenfassung:	The invention relates to an on-site drying method and drying system for an epoxy impregnated paper transformer. In the method, the epoxy impregnated paper transformer comprises an oil tank and an epoxy impregnated paper sleeve, wherein the oil tank is filled with transformer oil, and one end of the epoxy impregnated paper sleeve is immersed in the transformer oil; the transformer oil in the oil tank is heated to be not lower than 90 DEG C, so that the epoxy impregnated paper sleeve is heated and dried; in the process that the epoxy impregnated paper sleeve is heated and dried, gas in the epoxy impregnated paper sleeve is pumped out, and the epoxy impregnated paper sleeve is filled with protective gas; and after the step that the epoxy impregnated paper sleeve is filled with the protective gas, the moisture content of the gas in the epoxy impregnated paper sleeve and the insulation performance parameters of the epoxy impregnated paper sleeve are detected. By means of the method, the epoxy impregnated paper tra
