零相変流器の単線結線図では記号に３が書いてありますが、この意味はこの接続法を表しています。
ZCT is usually a neutral CT which happens to be determined by zero sequence present-day detection. What occurs in the course of leakage, the current in the phases are usually not a similar & for this reason the in is not equivalent to zero. This variation of existing flows into the neutral CT whicgh outings the RCCB
전류는 들어가고 나가는 전류의 크기는 동일합니다. 그러나 지락이 발생하면 전류가 정상적인
Now you have got understood that CBCT or zero sequencer are not employed just like we use a recent transformer.
Suited to energy transmission and distribution methods and intended to function with measuring or monitoring devices, or with protective relays, these bushing CTs (BCTs) can also be made use of with GIS or in conjunction with energy transformers bushings. Insulation tape or epoxy resin as insulation product.
絵を見ると地絡した相であるT相には地絡電流が流れていないように見えますが、

Vast frequency array: HY-ZCT is capable of measuring zero sequence current more than a wide frequency variety, which includes electrical power program frequencies and harmonics. This versatility enables them to seize and assess many kinds of faults and procedure disorders.
The essential principle of Functioning of zero sequence existing transformer is Kirchhoff’s present-day small: that is the sum of present 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

Large Linearity: The HY-ZCT is designed to more info offer a linear output in excess of a wide range of zero sequence latest. This linearity is vital for exact fault detection and coordination with protective relays.
Is it residual period enter or different CT input. The "ZCT" or residual will constantly begin to see the imbalance as well as the stage to floor fault present-day, but This really is also imbalance.
