racobb (Electrical) 11 Nov 09 21:12 I think your comprehension is Completely wrong. A CT just steps current and it's up to you to determine what the CT is measuring and type of relay you connect it to And exactly how you established the relay. Course is a certain style of relay, not a CT purpose or CT structure/relationship.
ZCT is often a neutral CT and that is based upon zero sequence recent detection. What takes place in the course of leakage, the current during the phases are certainly not the exact same & that's why the in is just not equal to zero. This change of latest flows to the neutral CT whicgh trips the RCCB

Even though We have now a three period method to shield, we only want one core in lieu of 3 if we utilize a CBCT or ZCT. This is extremely easy for installing and is easy.

. This can be a calculated value which takes under consideration the load (resistance) in the relay, resistance of your CT windings and resistance in the prospects:
スーパーキャパシタ 小型、大容量を実現した電気二重層キャパシタ。環境に優しい、簡易バックアップ電源としてＯＡ、ＡＶ機器の他、通信関連機器にも利用されています。
Core Stability Latest Transformer (CBCT) or Zero Sequence Current Transformer (ZCT) is really a Exclusive built existing transformer by using a condition of ring, utilized to detect the zero sequence present in the course of faults (for instance small circuit fault or floor fault) that generates an unbalanced inside our a few section procedure.
