零相変流器の単線結線図では記号に３が書いてありますが、この意味はこの接続法を表しています。

　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。

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。

Now you may have understood that CBCT or zero sequencer are usually not employed identical to we make use of a present-day transformer.

Zero sequence recent transformers are multipurpose in their software. They may be mounted on individual phases of a few-phase strains, handed by all a few-section conductors collectively, or put on the neutral line. This adaptability will allow them to effectively monitor the vector sum of three-section currents:

The resultant flux is zero (Φr = 0). This means there's no latest flowing through the secondary circuit of our CBCT. Its earth fault relay won’t get operated given that it is a usual Procedure.

With reducing-edge technological innovation, the HYCA sequence ensures speedy and correct detection of residual currents, contributing to the protection, longevity, and efficiency of the entire electrical method. In summary, the HEYI HYCA Residual Existing Sensor represents a benchmark in Form B residual latest sensing know-how, making certain best leakage current monitoring and Increased protection for charging piles throughout the world.

Nevertheless, when a ground fault site takes place, this harmony is disrupted. The fault generates a magnetic flux during the ring core of the ZSCT, inducing a voltage within the secondary side that activates the defense relay.
