Points to be considered before use12010080Re max60402000 0,5 1 1,5 2 2,5 3x Ce maxCurve 3:Reduction of response sensitivity when system leakage capacitances are greaterthan the maximum permissible value for C etaken from curve 2.When considering the curves, a point to be taken into account is that the sum of thecapacitances upstream of the individual measuring current transformer must amountto at least 50% of the total capacitance. Otherwise, a reduction in sensitivity must beexpected.The maximum system leakage capacitance is taken to be a value of 300 µFV. In a220 V system, therefore, this is 300 µFV/220 V = 1.4 µF. If the limit value isexceeded, there may be false trippings.33TGH1320E/03.2000
