This enables to optimization with the secondary turns in accordance with the helpful Principal pickup current of CT.
The best way ground fault is detected is by means of 50G (Pickup=2A, TD=all around 2sec) as well as by using the 59G and 67G, even so the designer describes the 59G/67G, is just for backup safety. The principal protection really should nevertheless be 50G, which somehow produced multiple GF when stage B was faulted (as revealed inside the relay log), for which the sytsme was registering mutilple floor faults "mysteriously" in other places downstream from the tie breaker (diagram). But in advance of I digressing into distinct matters, I want to point out dependant on the method I have explained to this point, are we using the right CT for this applications? Thanks.
Therefore, the magnetic flux needed to create a specific secondary recent is decreased to at least one-3rd (1/three), which can be the very best gain provided the enhanced In general sensitivity from the protective technique.

三相交流電源のそれぞれの相に流れる電流のベクトルの和は通常は対称であるためゼロとなりますが、地絡電流が流れた場合にはそのバランスが乱れてゼロ以外の値を持ちます。

This triggers a visit mechanism, efficiently isolating the faulted section to forestall damage and assure safety.
Now you've got comprehended that CBCT or zero sequencer are certainly not used much like we use a existing transformer.

そのためあらかじめ漏電遮断器に内蔵され、絶えず事故検知の役割を担っています。 零相変流器の使用用途
On top of that, as the a few stage technique latest is balanced, the amount of secondary turns of CT isn't necessary to produce the cable’s rated recent due to the fact no secondary present flows less than regular functioning problems.

The original explanation I made this submit was that all through a latest floor fault from the system, we uncovered that some of the relays had been tripping improperly (or mysteriously), that may be, a number of the upstream breakers have been tripped imagining it absolutely was a ahead fault latest, when in fact, and we thought, it should be reverse (i.
