In contrast to on an earth leakage breaker, there's no interruption performed and there is only an earth leakage detection functionality.
In an irregular situation, the sum on the three phase current is not zero. Considering that the program will become an unbalanced 3 period system, the zero sequence existing will start flowing while in the secondary winding of CBCT.

Through Ground Faults: From the occasion of the ground fault in one period, the ZSCT detects the sum of the unbalanced present as well as fault existing (Id), providing a transparent indicator from the fault issue.
Consequently the magnetic flux demanded with the creation of a selected secondary present-day is minimized to at least one-third (1/3), that's the greatest benefit as the overall sensitivity of your security technique is enhanced.
三相のいずれかに地絡電流が流れると、三相のバランスが崩れて零相電流はゼロとなりません。これにより地絡事故をただちに発見することができます。
両端接地を採用するポイントは、シールドに発生する誘起電圧の大きさです。
Since electric powered motors are delicate to surge existing that could make them split, CBCT is set zct up to stop any earth fault to impact the motor. Let’s say we have A 3 period motor, we install the CBCT with its Main staying handed through by all the a few stage motor wires.
Whilst in abnormal problems, the sum of section existing won't be zero. Then a result of the unbalancing of section present, a zero sequence recent will move during the secondary circuit of CBCT.

電気設備設計の基礎知識 電気計算の基礎となる幹線設計やケーブルの選定方法、配線器具の計画、電線管の種類と使い分け。
高圧ケーブルの両端を接地する方式です。高圧ケーブルの亘長が長い場合に採用されます。高圧ケーブルの亘長が長いと、非接地側に誘導電圧が発生して危険になります。これを防ぐ為に両端接地をします。

「零相変流器」は、こうした三相交流電源における零相電流を検出する装置です。
