このように設置すれば、高圧ケーブル以降の地絡を検知して保護することができます。

The resultant flux is zero (Φr = 0). This means there's no recent flowing from the secondary circuit of our CBCT. Its earth fault relay received’t get operated since this is a regular Procedure.

Because using a CBCT is to guard, we must always use it to shield sensitive electrical equipment or machines. Preserving them from your earth fault is a necessity in case you don’t want them to malfunction.

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。

Now you've understood that CBCT or zero sequencer are not made use of the same as we make use of a existing transformer.

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。

In this manner, we will likely not obtain any remainder of zero sequence recent while in the CBCT Principal winding. Because it can be a balanced three section, there won't be any flux produced within the CBCT Main. So, The existing while in the secondary winding is zero.

Zero sequence present-day transformers are functional within their software. They can be put in on specific phases of a few-period traces, handed via all a few-period conductors collectively, or placed on the neutral line. This adaptability enables them to proficiently check the vector sum of three-section currents:

The key position of ZSCTs is to boost system safety by detecting faults, especially floor faults and leakage currents. When these kinds of faults take place, the ZSCT activates, cutting off the ability supply to circumvent electrical shock hazards and machines problems.
