Made to do the job with measurement instruments to empower monitoring per IEC/IEEE standards, these current transformers supply thermal withstand approximately 40x nominal present for 1 next. Select mounting components to simplify installation as part of your particular software.
By doing this, we won't obtain any remainder of zero sequence present during the CBCT primary winding. As it is a well balanced a few section, there won't be any flux created in the CBCT core. Therefore, The present within the secondary winding is zero.
ZCT is usually a neutral CT which happens to be based upon zero sequence present-day detection. What takes place through leakage, The existing within the phases are usually not a similar & for this reason the in isn't equivalent to zero. This difference of latest flows into the neutral CT whicgh excursions the RCC
This can make ZSCTs indispensable in systems where ground fault detection is vital for safety and operational integrity.

회로를 통하지 않고 대지를 통해서 돌아갑니다. 이것을 누전 이라고도 합니다.
The way floor fault is detected is through 50G (Pickup=2A, TD=all around 2sec) and likewise by using the 59G and 67G, even so the designer describes the 59G/67G, is only for backup protection. The key security should really site nonetheless be 50G, which someway generated numerous GF when stage B was faulted (as proven inside the relay log), for which the sytsme was registering mutilple floor faults "mysteriously" in other places downstream of your tie breaker (diagram). But right before I digressing into different subject areas, I wish to point out based on the system I have explained to this point, are we using the ideal CT for this apps? Thanks.
このように電流の不平衡が生じることで地絡検出が可能なのですが、シールドがあることで地絡しても不平衡が起きなくなります。
したがって、通常状態（事故が生じていない）では変流器の２次側には電流は流れていません。電流の不平衡があっても、地絡事故が起きていない限りベクトル合成すると打ち消している状態になりますので、ＺＣＴ２次には電流は流れません。
ところが零相変流器では３相分（交流は通常３相交流で送電されています）の電線を一括して変流器に通しています。このように変流器に電線を通すと２次側にはどのような電流が流れるのでしょうか。
