３相分の電流を一括して変流器に通すと、３相分の電流をベクトル合成した電流が２次側に流れます。ベクトル合成された電流はどうなるのでしょうか？実は対称３相交流３相分の電流を合成させると”０”になるのです。対称３相交流は、各相とも同じ大きさでそれぞれが１２０°ずつ位相がずれているのでこのようになります。
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。
ZCT is really a neutral CT which can be determined by zero sequence recent detection. What happens through leakage, the current in the phases usually are not precisely the same & that's why the in is just not equal to zero. This variance of present-day flows to the neutral CT whicgh journeys the RCC

一般的な変流器と同様に、円環状の鉄心にコイルを巻き付けた構造を持ち、円環の中央に導体が貫通しています。
That's why earth fault relay connected Together with the secondary CBCT will get energized and it isolates the balanced technique with the assistance of a circuit breaker.
Timely detection of ground faults is essential to protecting against products problems, electrical hazards and method failures.
I am attaching the 750 link diagram, it displays the link system which matches our set up with the protect grounding routing In the CT window. Thanks on your suggestion, oldfieldguy!
「零相変流器」は、こうした三相交流電源における零相電流を検出する装置です。
Doing the job basic principle of CBCT or ZCT Kirchhoff's existing legislation states that the whole present-day at each and every node of an electrical circuit will equivalent zero is the basic tenet governing how zero sequence latest transformers operate. The vector sum of A 3-section program's section present (Ia + Ib + Ic = 0) is zero through regular operation. Thus, the first winding in the CBCT will likely not consist of any leftover zero sequence latest.
Main harmony CT is usually used for earth fault security (or site earth leakage protection) for medium voltage electrical techniques. A normal CBCT is as proven within the beneath figure.
一覧ページ 積層圧電アクチュエータ 圧電縦効果を利用して電気エネルギーを、変位や力などの機械的エネルギーに変換するセラミック素子。近年光通信分野の用途に期待がもたれております。
Could it be residual section input or independent CT enter. The "ZCT" or residual will generally begin to see the imbalance together with the section to floor fault present-day, but this is also imbalance.
