Made to do the job with measurement devices to empower monitoring for each IEC/IEEE expectations, these recent transformers deliver thermal stand up to around 40x nominal recent for one second. Choose mounting add-ons to simplify set up in your specific application.

最後にここまでのおさらいとしてもう一度変流器と零相変流器の違いを示します。
Zero sequence present-day transformer HY-ZCT is a present transformer specially utilized to evaluate or detect the zero sequence element of present-day in a few period power procedure.
11 Nov 09 09:52 Does anyone know how to notify whether or not a currnet transformer is for zero sequence sensing and just a standard CT? One example is, I'm thinking about the product site for just one mfr. The product or service page didn't point out anything at all related to zero sequence, so how do I am aware whether it is for The actual software i am searching for or not, Although it is actually lised less than ground sensing products classification.
With above forty five yrs of expertise and engineering collaboration with Germany's MWB, CIC is ISO certified and site features products and solutions acknowledged for dependability in various industrial programs.

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。
Quite a few approaches exist to dimension recent transformers. This Observe will take a look at numerous procedures, with individual notice becoming paid to safety course CTs sized in IEC 60044, which happens to be adopted internationally.
Ground Fault Detection: Among the list of major purposes on the HY-ZCT is ground fault detection. By measuring zero sequence present, these transformers can detect the existence of floor faults, which happen when current flows from the stage conductor to floor.

In the event the leakage latest at the CT Key reaches a specific level, the CT secondary provides the necessary existing sign or voltage signal – based on the style of protecting relay in use – for that defense of the ability technique. EZ Sequence
Due to this fact, the magnetic flux necessary to produce a specific secondary existing is reduced to 1-third (one/3), that is the very best advantage provided the enhanced Over-all sensitivity from the protective system.
