10、平均值的1%。The measurement will be taken with quick microhm meter of direct resistance or double bridges in all branch connectors, the mutual difference of all measurement results of all phases should be less than 2% of average values, the mutual difference of all measurement results of all phase-to-pha

11、se resistance should be less than 1% of average values,3 1.2 检查所有分接头的变压比：check voltage ratio of all branch connectors检查采用变压比电桥，其变压比的允许误差在额定分接头位置时为0.5%。Use voltage ratio bridge for checking, the tolerance of voltage ratio should be 0.5% in rated branch connectors。3 1.3 检查变压器的三相结线组别：check windings of

12、three phases wiring of transformer与检查变压比同时进行，必须与设计要求及铭牌上的标记和外壳上的符号相符。This job and checking of voltage ratio will be done synchronously, the results must be in accordance with designing requirements、 marks in nameplates and symbols in outside shell。3 1.4测量绕组连同套管及铁芯的绝缘电阻与吸收比：Measure insulation resista

13、nce and absorption ratio of windings casings and iron cores。采用2500/500V兆欧表进行测量，绝缘电阻值不应低于产品出厂试验值的70%。Use megohmmeter of 2500/500V for measurement, the insulation resistance values should not be less than 70% of experimental values of production delivery。3 1.5 绕组连同套管的交流耐压：AC voltage endurance of windi
