The decentralization of sampled value and the uncertainty of sampled time bring forth the action fuzzy area of sampled value current differential protection.
电流数据采样的离散性和采样初始时刻的不确定性是导致采样瞬时值电流差动保护动作值模糊区产生的根本原因。
The zero level of corresponding point is subtracted from sampled value 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.
要测试它是否合理运作，将 CPU 值从 10 改为 100，以便在每次采样情景时触发它。
