摘　　要：依据轨道绝缘在线测试仪在现场使用的特点,采用直接比较法进行校准,校准过程中采用信号发生器等设备模拟现场的各种影响量。通过试验和不确定度分析,设计出满足现场使用要求的校准方法,解决轨道绝缘在线测试仪的量值溯源问题。According to the characteristics of in-circuit tester for track insulation in field use, direct comparison method is adopted for calibration. During the calibration, signal generator and other equipment are used to simulate various impacts on the field. Through test and uncertainty analysis, a calibration method is designed to meet the re- quirements of field use and solve the problem of metrological traceability of in-circuit tester for track insulation.
