三相交流電源のそれぞれの相に流れる電流のベクトルの和は通常は対称であるためゼロとなりますが、地絡電流が流れた場合にはそのバランスが乱れてゼロ以外の値を持ちます。
下図は「非接地系統（＝６ｋＶ系統）」で地絡事故が生じたときの電流の分布です。

From its perform, you might be able to decide how CBCT or ZCT works. The CBCT or ZCT operates by balancing zero sequence present-day in almost any three stage procedure. Here is the principal theory we want to remember just before jumping to the subsequent rationalization.
Thank, for your details, I desire to ask you a question, in MV Program the relay that's connected to the CBCT, must have the directional overcurrent defense possibility ?

Haven't got usage of the manual now but I'm fairly positive that the 750 also internally calculates the residual (imbalance) from the phase currents(most microprocessor relays do this). I believe the manual will call the calculated residual fifty/51N versus fifty/51G. Or a little something like that. Alan

Some ideas on how to use hysteresis loop characteristics in the manufacture of current transformers Some suggestions regarding how to use hysteresis loop properties in the manufacture of current transformers A current transformer (CT) is an electrical device utilized to evaluate or watch alternating latest (AC) in a power program. Its working principle is predicated on using the hysteresis qualities of magnetic resources
