３相分の電流を一括して変流器に通すと、３相分の電流をベクトル合成した電流が２次側に流れます。ベクトル合成された電流はどうなるのでしょうか？実は対称３相交流３相分の電流を合成させると”０”になるのです。対称３相交流は、各相とも同じ大きさでそれぞれが１２０°ずつ位相がずれているのでこのようになります。
ZCT is really a neutral CT which can be determined by zero sequence existing detection. What occurs throughout leakage, the current during the phases are certainly not the exact same & that's why the in just isn't equivalent to zero. This variance of recent flows in to the neutral CT whicgh visits the RCCB

"Security" CT's are built so that you can preserve accuracy at latest ranges much in surplus in their nominal values, usually 20 moments nominal, in order to insure suitable illustration of currents less than fault circumstances.
電気設備の保守管理の仕事に携わっています。専門知識ってネットでは出てこないか、難しすぎるって場合がおおくないですか？そこで私は電気関係の仕事で役立ちそうな情報を簡単に分かりやすく発信しています。
With above 45 several years of experience and technological know-how collaboration with Germany's MWB, CIC is ISO Qualified and delivers items regarded for dependability in many industrial programs.
Also, since the three section method existing is balanced, the volume site of secondary turns of CT is just not needed to deliver the cable’s rated existing for the reason that no secondary present-day flows under normal operating situations.
専門用語の解説 家電のルミネセンスを理解する ルミネセンスとは、材料が光を放つ現象のことです。この光は、エネルギーを吸収した材料が、エネルギー準位がより低い状態に遷移することで放出されます。ルミネセンスは、外部からのエネルギー源（光、電流、熱など）の存在がなければ発生しません。

Symmetrical Main Design and style: HY-ZCT normally use a symmetrical Main design and style to be sure equal magnetic coupling for all a few phases. This style and design lowers the error because of magnetic unbalance and enhances the accuracy of zero sequence present-day measurement.

As opposed to The standard existing transformer, the CBCT receives its primary winding with the a few stage wires passing in the ring at its Centre of your iron Main. Its secondary winding is wound to the ring formed iron Main and connected to the earth fault relay.

Therefore, the magnetic flux required to produce a particular secondary existing is decreased to 1-3rd (1/three), which can be the best advantage specified the enhanced In general sensitivity in the protecting program.
