三相交流電源のそれぞれの相に流れる電流のベクトルの和は通常は対称であるためゼロとなりますが、地絡電流が流れた場合にはそのバランスが乱れてゼロ以外の値を持ちます。

In distinction, the whole stage existing will not be zero under abnormal circumstances. A zero sequence present-day will then move during the CBCT secondary circuit as the period recent is from stability.

The impact of ( Īsheath + Īearth ) is canceled when the earthing potential customers are taken throughout the eye of CBCT. Consequently the protection plan responds only to (Īa + Īb + Īc) present in the induction motor.

Nominal CT ratio, making certain The present is sufficient to work the earth fault relay whether or not the ground fault may be very compact.

Array of CBCT or ZCT The subsequent conditions are used to pick the best zero sequence CT or CBCT. Nominal CT ratio: This could be established to make sure that, even in the case of a minimal floor fault, There's ample present-day to run an earth fault relay.

Nominal CT ratio: This should be such that even in smallest ground fault The present must be enough to operate earth fault relay.

三相のいずれかに地絡電流が流れると、三相のバランスが崩れて零相電流はゼロとなりません。これにより地絡事故をただちに発見することができます。

継電器（リレー）や遮断器とともに漏電遮断器に内蔵されることが多く、事故や火災などの災害につながる漏電を防ぐ上で重要な役割を担っています。 参考文献

Zero sequence recent transformers work to the ideas outlined by Kirchhoff’s Existing Legislation, which states that the algebraic sum of your currents moving into a node ought to equivalent zero less than typical circumstances.

Due this website to this fact, the magnetic flux necessary to make a certain secondary present is decreased to at least one-3rd (one/three), which is the very best gain provided the improved General sensitivity from the protecting method.
