零相変流器の構造について説明します。零相変流器は通常の変流器とほとんど変わりません。使い方が違います。まず下の絵をご覧下さい。

Relay defense coordination: HY-ZCT performs an important role in relay safety coordination. By properly measuring the residual present less than fault problems, they offer input to protective relays to initiate appropriate protective action.

This functionality is significant for precise present measurement and method defense, making certain that checking products and protective relays run properly with out staying subjected to higher existing stages.

Choice of CBCT or ZCT The subsequent standards are used to pick the finest zero sequence CT or CBCT. Nominal CT ratio: This should be established to ensure, even in the situation of a minimal ground fault, There may be adequate present-day to operate an earth fault relay.

Minimal stress: ZCT is created to Use a low burden, which means that they do not considerably influence the Procedure with the circuit or maybe the accuracy of other measurement units from the procedure.

したがって、通常状態（事故が生じていない）では変流器の２次側には電流は流れていません。電流の不平衡があっても、地絡事故が起きていない限りベクトル合成すると打ち消している状態になりますので、ＺＣＴ２次には電流は流れません。

I noticed During this article that a metering class cannot be applied for defense. What issues could maybe In either case if the CT's are replaced in apps.  

 Core equilibrium CT is usually employed for earth fault security (or earth leakage safety) for medium voltage electrical devices. A typical CBCT is as demonstrated inside the down below figure.

  The power of your CT and relay to work under these circumstances is actually a purpose of K’scc plus the transient general performance of the relay, Ktd.  The aspect, Ktd is supplied by the relay manufacturer.  Correct working is accomplished by guaranteeing the go here subsequent is legitimate:
