There is a slight complication while in the producers know their relays much better than we (or perhaps the IEC) do.  As general assistance, you'll want to normally seek advice from the producers information:

The initial purpose I built this submit was that through a new floor fault in the system, we found out that a few of the relays had been tripping incorrectly (or mysteriously), that's, a few of the upstream breakers have been tripped contemplating it absolutely was a ahead fault recent, when in fact, and we believed, it should be reverse (i.

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。

Now you've got recognized that CBCT or zero sequencer are not utilized just like we utilize a latest transformer.

Nominal CT ratio, ensuring that The existing is enough to function the earth fault relay even when the ground fault is quite modest.

Symmetrical this site Main Layout: HY-ZCT ordinarily make use of a symmetrical core style and design to guarantee equal magnetic coupling for all 3 phases. This structure lowers the error a result of magnetic unbalance and enhances the precision of zero sequence present measurement.

Compared with the typical latest transformer, the CBCT gets its Key winding with the 3 section wires passing with the ring at its Heart in the iron core. Its secondary winding is wound to your ring shaped iron core and connected to the earth fault relay.

However, any time a ground fault occurs, this stability is disrupted. The fault generates a magnetic flux from the ring Main of the ZSCT, inducing a voltage within the secondary facet that activates the defense relay.

Not like The present transformer (CT), the key winding of CBCT is shaped with three Main cables passing through the Heart of its iron core plus the secondary coil of CBCT is also wounded on its ring-style iron Main, and it's connected with earth-fault relay.
