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。
この地絡電流が流れ続けているところで、零相変流器へ流れる電流をご覧下さい。零相変流器のところを流れる電流のバランスがくずれています。これによって零相変流器２次側には電流が流れるということです。
零相変流器の二次側に電流が流れる時は、３相の電流のバランスが崩れて、打ち消すことができない時となります。なぜバランスがくずれるのでしょうか。それは、電気回路に１線地絡事故（３相の電線のうち１本の電線から電気が大地に流れた状態）が発生したときということになります。

11 Nov 09 09:52 Does any individual know how to notify whether or not a currnet transformer is for zero sequence sensing and just a normal CT? For instance, I am investigating the solution page for one particular mfr. The solution webpage didn't point out anything connected with zero sequence, so how do I understand if it is for the particular application i am in search of or not, even though it's lised under floor sensing product or service classification.
The earth link of our motor will probably be handed to your Main of your CBCT with the cable sheath. The commonest three section motor which has a CBCT might be seen beneath. You may also notice what CBCT present-day transformer is.
The Main equilibrium present transformer (CBCT) is principally employed for earth fault defense of electrical equipment. Amongst its crucial applications is earth fault security of induction motors, that's talked over down below intimately.

For a better comprehension, We're going to attempt to put anything We have now examine earlier mentioned into a mathematical concept.
The existing transducer epitomize precision and adaptability in fashionable industrial instrumentation. Its correct recent measurement and conversion capabilities present very important operational knowledge through standardized alerts. From sign isolation guarding towards electrical sounds to Highly developed interaction protocols, The existing transducer adapt to control networks. Modular design and style aids integration, though twin output selections harmonize with getting equipment.

Therefore, the magnetic flux necessary to produce a specific secondary recent is lowered to at least one-third (one/3), which this website is the very best advantage specified the enhanced Total sensitivity with the protective process.
