根据DL/T475-2006《接地装置特性参数测量导则》测量跨步电压的方法，通过大电流发生器模拟一个故障电流给被测物体，再用内置等效人体电阻的电压表对模拟人体双脚的电极进行了跨步电压的测量，并找出了其降低措施，为以后跨步电压的测量提供参考。
근거DL/T475-2006《접지장치특성삼수측량도칙》측량과보전압적방법，통과대전류발생기모의일개고장전류급피측물체，재용내치등효인체전조적전압표대모의인체쌍각적전겁진행료과보전압적측량，병조출료기강저조시，위이후과보전압적측량제공삼고。
Step voltage is the voltage between legs of people who walkaroundthecurrent potential distribution area where the ground current isintoearthwhen the electrical equipment occurs a ground fault .Though it di-rectly touches the power supply and the voltage is slightly lower compared to the charged body ,the caused harm degree is also very serious if the rescue is not timely or rescue method is improper .According tothe method provided byGuide of Measuring Grounding Device Parameters (DL/T475 -2006) ,this articlesimu-lates a fault current throughthehigh -current generator to the objectto be measured ,andthen usesthe voltme-ter with built - inhuman - equivalent resistanceto determinethe step voltageofelectrodessimulatinghuman feet ,as well as findsoutreduction measures ,so as to provide references for step voltage measurements in fu-ture .
