跨步电压的危害线路断落时，电流入地的情况就象一块石头被投入水里那样，会出现很多圆圈，离圆心越近的地方，电位越高，同一圆圈的电位则是相同的。如果有人走进这些圆圈，两只脚承受的电压就形成了跨步电压。当人接触到跨步电压时，电流将通过人体，出现跨步电压触电。... The voltage step-by-step When the line is broken down, the current into the ground is like a stone being thrown into the water. There will be many circles, the closer to the center of the circle, the higher the potential and the same circle will have the same potential. If someone enters these circles, the voltage that the two feet bear will form the step voltage. When people touch the step voltage, the current will pass through the body, there is a step voltage electric shock. ...
