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。
T相には地絡点から対地静電容量を通って地絡電流は流れないのでしょうか。
From its functionality, you could possibly figure out how CBCT or ZCT functions. The CBCT or ZCT works by balancing zero sequence current in almost any a few phase system. Here is the major principle we'd like to recollect in advance of leaping to the subsequent rationalization.
Thank, for your data, I need to check with you a matter, in MV Procedure the relay that's connected to the CBCT, must have the directional overcurrent defense alternative ?

Variety B residual present sensor：The HYCA series by HEYI business stands as an Extraordinary Answer for charging pile apps, Compliant with arduous Intercontinental specifications such as IEC 62955, IEC 62752, and UL 2231, the HYCA series excels in providing precise and in depth leakage present monitoring.
専門用語の解説 再生可能エネルギーとは？わかりやすく解説 再生可能エネルギーとは、自然界に存在する無限に再生可能な資源を利用して発電する方法です。太陽光、風力、水力、地熱、バイオマスなどの自然現象や物質を活用し、エネルギーを産出します。化石燃料とは異なり、枯渇することがなく、環境にやさしいのが特徴です。このため、持続可能なエネルギー源として世界中で注目を集めています。

Doing the job theory of CBCT or ZCT Kirchhoff's present law states that the whole current at each node of an electrical circuit will equivalent zero is the basic tenet governing how zero sequence recent transformers function. The vector sum of A 3-section process's section recent (Ia + Ib + Ic = 0) is zero all through typical Procedure. As a result, the main winding of your CBCT will not consist of any leftover zero sequence latest.

Frequency reaction: ZCT is made to work above an array of frequencies, commonly from 50Hz to 400Hz, which makes them appropriate for use in a number of applications.
If the leakage latest in the CT Major reaches a certain amount, this website the CT secondary gives the mandatory recent signal or voltage sign – based on the form of protective relay in use – to the defense of the facility method. EZ Series
The vector sum of A 3-period system’s section recent (Ia + Ib + Ic = 0) is zero during regular Procedure. Therefore, the first winding with the CBCT is not going to include things like any leftover zero sequence recent.
