The decentralization of sampledvalue and the uncertainty of sampled time bring forth the action fuzzy area of sampledvalue current differential protection.
The zero level of corresponding point is subtracted from sampledvalue to eliminate the zero fluctuation and multiplied by compensating coefficient to modify the sensitivity fluctuation.
通过减去对应点的零位水平可消除零位波动,然后和补偿系数相乘来修正灵敏度波动;

To test that it works properly, change the CPU value from 10 to 100 so it will be triggered every time the situation is sampled.
