Thank, for your personal information, I wish to question you an issue, in MV Technique the relay which happens to be linked to the CBCT, ought to have the directional overcurrent security option ?

二次端子が開放状態になると二次端子に高電圧が発生し、絶縁の破壊による巻線の破損、計器の破損を起こす危険がある。

  The way floor fault is detected is via 50G (Pickup=2A, TD=about 2sec) and also by way of the 59G and 67G, on the other hand the designer clarifies the 59G/67G, is only for backup safety.  The key defense should continue to be 50G, which someway generated numerous GF when section B was faulted (as revealed while in the relay log), for which the sytsme was registering mutilple floor faults "mysteriously" elsewhere downstream of your tie breaker (diagram).  But before I digressing into distinct topics, I want to point out depending on the method I've described to this point, are we using the ideal CT for this applications?  Many thanks.   

ベクトルの和の平均値は「零相電流」と呼ばれ、上記のような対称形の場合、零相電流はゼロとなります。

電気設備に備えられた電路が大地と電気的に接続されると、その箇所に地絡電流として大電流が流れ込むため、重大な事故につながるリスクがあります。

　ところが零相変流器では３相分（交流は通常３相交流で送電されています）の電線を一括して変流器に通しています。このように変流器に電線を通すと２次側にはどのような電流が流れるのでしょうか。

Since electrical motors are delicate to surge current which will make them break, CBCT is set up to forestall any earth fault to impact the motor. Permit’s say We have now a three stage motor, we install the CBCT with its core being passed via by each of the 3 phase motor wires.

Could it be residual stage input or different CT enter.  The "ZCT" or residual will usually begin to see the imbalance and also the section to ground fault recent, but This really is also imbalance.

Rct - secondary winding d.c. resistance at specified temperature Rb  - rated resistive burden of your relay R’b - Rleads + Rrelay;  This really is thel linked load CTs need in order to offer the demanded recent to check here push the relays throughout transient fault circumstances.
