　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。

By doing this, we will likely not come across any remainder of zero sequence existing inside the CBCT Principal winding. Because it is often a well balanced 3 phase, there won't be any flux created within the CBCT Main. So, the current while in the secondary winding is zero.

The influence of ( Īsheath + Īearth ) is canceled once the earthing prospects are taken from the eye of CBCT. As a result the security plan responds only to (Īa + Īb + Īc) existing while in the induction motor.

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。

二次端子が開放状態になると二次端子に高電圧が発生し、絶縁の破壊による巻線の破損、計器の破損を起こす危険がある。

Let Īa, Īb, and Īc be line currents of A 3-period process and Φa, Φb, and Φc are corresponding parts of magnetic flux developed within the Main of zero sequence CT or CBCT.

「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。

As a result, no flux will arise during the Main of here CBCT. Due to this fact, the secondary circuit with the CBCT might be totally static.

(2) The relay complies with CE marking kind MITSUBISHI MCCB with a voltage tripping product to interrupt recent for the duration of ground fault.

Frequency reaction: ZCT is intended to function about a wide array of frequencies, generally from 50Hz to 400Hz, which makes them ideal for use in a variety of programs.

As opposed to the current transformer (CT), the key winding of CBCT is formed with three Main cables passing throughout the Centre of its iron core plus the secondary coil of CBCT can be wounded on its ring-type iron Main, and it is linked with earth-fault relay.
