低圧の一般計器用としても用いられますが、より高電圧の電路ほど事故の程度も大きくなりかねないことから、零相変流器の役割は必須のものとしてより重要になります。 零相変流器の原理

The vector sum of a three-phase procedure’s period latest (Ia + Ib + Ic = 0) is zero through regular Procedure. Consequently, the primary winding in the CBCT will not likely consist of any leftover zero sequence present-day.

 Main harmony CT is mostly useful for earth fault defense (or earth leakage protection) for medium voltage electrical techniques. An average CBCT is as revealed while in the beneath determine.

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

サブ変電所で地絡保護をする場合で、シールドの接地がサブ受電所の場合。

Now you may have comprehended that CBCT or zero sequencer are certainly not utilized similar to we make use of a latest transformer.

From its purpose, you may be able to find out how CBCT or ZCT will work. The CBCT or ZCT is effective by balancing zero sequence latest in almost any a few section procedure. This is actually the primary theory we want to recollect prior to jumping to the next explanation.

Zero sequence present-day transformers operate within more info the rules outlined by Kirchhoff’s Latest Regulation, which states the algebraic sum with the currents getting into a node have to equivalent zero underneath usual ailments.

The fundamental principle of Operating of zero sequence present-day transformer is Kirchhoff’s latest small: that's the sum of present-day at any node of the electrical circuit are going to be equal to zero.

サブ変電所で地絡保護をする場合で、シールドの接地がメイン受電所の場合。

Comparing, equation (five) with equation (3) we acquired which the net magnetic flux inside the Main of CBCT won't be zero. It has some finite worth that may induce present-day within the secondary circuit of ZCT.
