Whilst in irregular circumstances, the sum of stage existing will not be zero. Then due to unbalancing of period latest, a zero sequence latest will stream in the secondary circuit of CBCT.
In contrast to your present transformer (CT), a CBCT’s Key winding is made from a three-Main cable that runs in the Centre of its iron Main, and its secondary coil is wrapped on a ring-formed iron core that may be linked to an earth fault relay.
Subsequently, the CBCT’s secondary-connected earth fault relay will become activated, isolating the health and fitness system with a circuit breaker.

零相変流器の２次側に保護継電器を設置しておき、電流が流れたら遮断器を開放するようにしておけば地絡事故発生した場合に迅速に故障箇所を電気回路から切り離すことができます。これが零相変流器の設置目的と使用法です。
With above forty five several years of experience and know-how collaboration with Germany's MWB, CIC is ISO certified and delivers goods recognized for trustworthiness in a variety of industrial apps.
Furthermore, as the a few stage procedure existing is well balanced, the amount of secondary turns of CT is not really essential to supply the cable’s rated present for the reason that no secondary existing flows less than regular running circumstances.
I am attaching the 750 connection diagram, it exhibits the link approach which matches our set up With all the protect grounding routing In the CT window. Thanks for your idea, oldfieldguy!
The essential theory of Performing of zero sequence present transformer is Kirchhoff’s current reduced: that's the sum of existing at any node from the electrical circuit might be equivalent to zero.
そのためあらかじめ漏電遮断器に内蔵され、絶えず事故検知の役割を担っています。 零相変流器の使用用途

The current transducer epitomize precision and adaptability in contemporary industrial instrumentation. Its accurate current measurement and conversion abilities deliver critical operational details as a result of standardized indicators. From signal isolation guarding against electrical sounds website to Highly developed conversation protocols, the current transducer adapt to manage networks. Modular style and design aids integration, when dual output alternatives harmonize with receiving machines.

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。
