健全な電路では零相変流器の二次側は電流が平衡しており流れることがないが、三相を一括で通した電路に地絡が発生した場合、零相変流器に流れる電流のバランスが崩れ、二次側に電流が発生する。発生した電流バランスの崩れを検出するのが零相変流器の役割である。零相変流器の二次側には地絡継電器などの保護装置が設置され、故障電流の検出といった電路保護に使用される。

Nominal CT ratio, ensuring that the current is sufficient to run the earth fault relay regardless of whether the bottom fault is incredibly little.

Compared with the typical present transformer, the CBCT gets its Most important winding within the 3 stage wires passing through the ring at its Centre with the iron core. Its secondary winding is wound towards the ring formed iron core and linked to the earth fault relay.

From its operate, you may be able to find website out how CBCT or ZCT operates. The CBCT or ZCT is effective by balancing zero sequence existing in any 3 period system. This can be the major principle we want to recall before leaping to the subsequent explanation.

In contrast to some present-day transformer (CT), a CBCT’s Key winding is made from a three-core cable that runs from the Centre of its iron Main, and its secondary coil is wrapped on a hoop-formed iron Main that's connected to an earth fault relay.
