A current transformer is used to action up or move down alternating existing, wherever CBCT or zero sequencer is used as fault protection.

is fairly quick to be aware of and relates to the liner portion of a CT characteristic.  The voltage and present across a CT are linear only up till a particular price (Usually specified being a many of your nominal rating),  and then the CT will saturate and the curve will stage off.

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。

IEC 60044 specifies the necessities for cover CTs (Together with measuring CT's, VTs and electronic sensors). The key to CT dimensioning beneath the regular, is the symmetrical small circuit existing and transient dimensioning variables:

The earth link of our motor might be handed to the core with the CBCT in the cable sheath. The most common three stage motor that has a CBCT is usually seen beneath. It's also possible to observe what CBCT present transformer is.

Permit Īa, Īb, and Īc be line currents of A 3-phase process and Φa, Φb, and Φc are corresponding parts of magnetic this site flux formulated during the Main of zero sequence CT or CBCT.

Assuming that CBCT is running while in the linear location, then the magnetic flux made during the Main of CBCT is going to be right proportional to its corresponding line recent. Consequently it can be written as:
