Compared with on an earth leakage breaker, there isn't any interruption carried out and There is certainly only an earth leakage detection purpose.
このように設置すれば、高圧ケーブル以降の地絡を検知して保護することができます。
零相変流器は一般的に貫通型が採用されており、鉄心内に三相導体を一括で通し、二次巻線をその上に巻いて磁気的な平衡を保っている。一般的な変流器と違い、零相変流器は三相導体を一括で通している。

"Safety" CT's are constructed to be able to preserve precision at existing ranges far in surplus of their nominal values, usually twenty occasions nominal, in an effort to insure correct illustration of currents beneath fault conditions.
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。

Unlike The everyday present-day transformer, the CBCT receives its Most important winding with the a few period wires passing from the ring at its center from the iron Main. Its secondary winding is wound on the ring formed iron Main and linked to the earth fault relay.
省エネルギーと脱炭素 カーボンニュートラルを達成し、二酸化炭素の排出を削減と吸収の技術について解説。
Internet resultant flux (Φr = 0) is zero. It means no recent will flow inside the secondary circuit of CBCT. For this reason earth fault relay will not function in standard healthy situations.
In this way, we will never come across any remainder of zero sequence current within the CBCT Main winding. Because it is actually a balanced three section, there won't be any flux created from the CBCT Main. So, The existing while in the secondary winding is zero.
Zero sequence current transformers are functional within their software. They can be put in on specific phases of a few-stage lines, handed via all three-period conductors collectively, or placed on the neutral line. This adaptability makes it website possible for them to successfully watch the vector sum of three-period currents:
