You will find there's slight complication from the manufacturers know their relays much better than we (or the IEC) do. As normal information, you need to often check with the producers information:
この地絡電流が流れ続けているところで、零相変流器へ流れる電流をご覧下さい。零相変流器のところを流れる電流のバランスがくずれています。これによって零相変流器２次側には電流が流れるということです。
Electrical Engineering What's the formulation for calculating limited circuit present-day in an influence program?

零相変流器の２次側に保護継電器を設置しておき、電流が流れたら遮断器を開放するようにしておけば地絡事故発生した場合に迅速に故障箇所を電気回路から切り離すことができます。これが零相変流器の設置目的と使用法です。
회로를 통하지 않고 대지를 통해서 돌아갑니다. 이것을 누전 이라고도 합니다.
The ZCT is dealt with like every other CT: ratio, polarity, accuracy course (saturation). The sole consideration that is often distinct is the Actual physical dimensions from the window because you're going to run zct all three section cables by that window.
ベクトルの和の平均値は「零相電流」と呼ばれ、上記のような対称形の場合、零相電流はゼロとなります。
何らかの原因で３相の電流のバランスが乱れると、コイルに二次電流が瞬間的に流れ、地絡として検出されます。
. This is the calculated price which takes into consideration the stress (resistance) in the relay, resistance of the CT windings and resistance on the potential customers:
三相のいずれかに地絡電流が流れると、三相のバランスが崩れて零相電流はゼロとなりません。これにより地絡事故をただちに発見することができます。
Core Harmony Recent Transformer (CBCT) or Zero Sequence Current Transformer (ZCT) can be a special built current transformer which has a condition of ring, utilized to detect the zero sequence existing throughout faults (for instance shorter circuit fault or ground fault) that generates an unbalanced inside our 3 stage system.

Also, The amount of secondary turns of CT isn't required according to the rated latest of the cable because no secondary latest flows in usual working conditions as being the 3 phase process currents are balanced.
