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。
対地静電容量を通じて流れた電流は受電設備の変圧器巻線を通って地絡した相に向かって流入し、地絡点に向かって流れます。地絡電流はこうして流れ続けます。

Zero sequence existing transformer HY-ZCT is actually a present transformer specifically used to measure or detect the zero sequence element of present-day in a few section energy program.
Zero sequence existing transformers are functional of their software. They may be mounted on individual phases of three-phase strains, handed through all three-phase conductors collectively, or put on the neutral line. This adaptability allows them to successfully keep track of the vector sum of three-phase currents:
Built to safeguard the facility program versus leakage and earth faults, these zero-phase recent transformers (ZCT) come in several window diameters. Epoxy-cast coil. CIC is really an industrial quality existing transformers, voltage transformers, distribution transformers, epoxy insulators and ability capacitors producer from Taiwan. With about 45 a long time of experience and technology collaboration with Germany's MWB, CIC is ISO Licensed and presents goods acknowledged for trustworthiness in various industrial programs.
Permit Īa, Īb, and Īc be line currents of a three-phase method and Φa, Φb, and Φc are corresponding elements of magnetic flux created inside the core of zero sequence CT or CBCT.
Small burden: ZCT is created to Use a small burden, which means that they do not drastically have an affect on the operation from the circuit or even the precision of other measurement this website products during the procedure.

Due to the fact using a CBCT is to shield, we must always utilize it to shield delicate electrical equipment or equipment. Preserving them within the earth fault is a necessity for those who don’t want them to malfunction.
It saied the moment, but I talk to all over again, are you currently Examine that grounding concentrator of cable back again to grounding by way of ZCT?
一覧ページ 積層圧電アクチュエータ 圧電縦効果を利用して電気エネルギーを、変位や力などの機械的エネルギーに変換するセラミック素子。近年光通信分野の用途に期待がもたれております。
Having said that, each time a floor fault occurs, this harmony is disrupted. The fault generates a magnetic flux within the ring core of your ZSCT, inducing a voltage within the secondary facet that activates the safety relay.
