racobb (Electrical) eleven Nov 09 21:twelve I do think your being familiar with is wrong. A CT just steps present-day and it is up to you to ascertain just what the CT is measuring and type of relay you connect it to And just how you established the relay. Route is a particular sort of relay, not a CT perform or CT style/link.
Using this method, we will not uncover any remainder of zero sequence current while in the CBCT primary winding. Since it is really a balanced 3 section, there will not be any flux generated inside the CBCT Main. So, the current in the secondary winding is zero.
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。
電気の仕事を始めたばかりの人に役立つサイトを目指しますのでよろしくお願いいたします。
零相変流器の２次側に保護継電器を設置しておき、電流が流れたら遮断器を開放するようにしておけば地絡事故発生した場合に迅速に故障箇所を電気回路から切り離すことができます。これが零相変流器の設置目的と使用法です。
Accuracy: ZCT is designed to deliver exact measurements of the zero-sequence ingredient of the present, even while in the existence of significant levels of sound or interference.

A ZCT is put in in the Neutral-Earth bonding conductor. It's going to initiate a visit only when neutral current is returned with the Protecting Earth conductor rather then the load neutral conductor. This ordinarily takes place when There's section-earth leakage (or fault). This safety only is effective properly in Immediate earthed installations (not Adult men).

Due to this fact, no flux will arise from the Main of CBCT. Consequently, the secondary circuit with the CBCT is going to be absolutely static.
Ground Fault Detection: One of many key programs with the HY-ZCT is ground fault detection. By measuring zero sequence present, these transformers can detect the presence of floor faults, which manifest when existing flows from a stage conductor to ground.
This ring style recent site transformer is able to equilibrium the zero sequence recent inside the a few stage program. This is where it got its name for a Zero Sequence Current Transformer (ZCT).
This coordination aids isolate faulty aspects of the procedure, minimizing downtime and defending tools from harm.
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。
