For a greater knowledge, We are going to attempt to put every little thing We now have go through previously mentioned into a mathematical theory.

The vector sum of a three-phase system’s section latest (Ia + Ib + Ic = 0) is zero throughout normal Procedure. Thus, the principal winding from the CBCT won't consist of any leftover zero sequence present-day.

丸窓型・トラック型・分割型など、長い歴史で培われた生産技術で、規格外品であっても様々なご提案をさせていただきます。

The resultant flux is zero (Φr = 0). This means there is absolutely no latest flowing through the secondary circuit of our CBCT. Its earth fault relay won’t get operated given that that is a ordinary Procedure.

전류는 들어가고 나가는 전류의 크기는 동일합니다. get more info 그러나 지락이 발생하면 전류가 정상적인

これを防ぐために零相変流器は使用されており、地絡電流を検出した場合に地絡箇所をただちに周囲から切り離すという機能を持っています。

この様に色々な役割がありますが、今回の内容で大事なのは最後の「地絡時の電流の帰路となる」です。

Due to this fact, the CBCT’s secondary-related earth fault relay will develop into activated, isolating the wellbeing technique with a circuit breaker.

2nd, Examine if capacitive present of cable is lower than your location. 2A looks is low location, for cable dimensions, from 120mm^2 is less than 1km lenght.

高圧ケーブルの絶縁物が劣化して地絡したとします。そうするとシールドが接地されているので、地絡電流はシールドを通って大地に流れます。

회로를 통하지 않고 대지를 통해서 돌아갑니다. 이것을 누전 이라고도 합니다.

ケーブルの途中で地絡したと仮定すると、地絡電流はシールドを通して接地点へ流れます。

상세하게 안내해 드리지 못하는 점 양해 부탁 드립니다. 모두가 행복한 인터넷

Assuming that CBCT is functioning while in the linear area, then the magnetic flux made during the core of CBCT might be immediately proportional to its corresponding line present-day. That's why it might be prepared as:
