A current transformer is used to step up or move down alternating existing, in which CBCT or zero sequencer is utilized as fault defense.

T相には地絡点から対地静電容量を通って地絡電流は流れないのでしょうか。

"Safety" CT's are produced to be able to sustain accuracy at current ranges much in surplus of their nominal values, normally 20 times nominal, to be able to insure correct illustration of currents underneath fault situations.

IEC 60044 specifies the requirements for defense CTs (Besides measuring CT's, VTs and electronic sensors). The true secret to CT dimensioning beneath the conventional, could be the symmetrical brief circuit present and transient dimensioning things:

電流には必ず行きと帰りがあり、通常その電流の大きさは同じになります。しかし地絡が発生すると、電流が正常な回路を通らずに大地を通って帰っていきます。これを漏電とも表します。

We'll predominantly use such a present transformer as an earth fault protection for medium level voltage distribution. The popular CBCT illustration can be found underneath.

The phase latest from among a few cables could have an unbalanced benefit. this website As a result the zero sequence current will come about inside the secondary winding and circuit of CBCT.

Considering the fact that using a CBCT is to shield, we should utilize it to protect delicate electrical gadgets or machines. Guarding them from your earth fault is a necessity should you don’t want them to malfunction.

なお、下の記事は私（管理人）が書いた超概念的な内容です。もっと理論的な解説は鹿の骨さんが下さった以下を参照ください。

The earthing prospects in the cable sheath to earth and should be taken with the eye in the ZCT core. A typical diagram is as shown in the below determine.

The 750 also enables you to setups fifty/51N things utilizing a derived value within the 3 stage inputs.  They are set up as "Neutral Present-day" from the setpoints.
