A present-day transformer is used to stage up or phase down alternating latest, where by CBCT or zero sequencer is used as fault safety.
By doing this, we will never obtain any remainder of zero sequence present while in the CBCT primary winding. Since it can be a well balanced a few phase, there will not be any flux produced from the CBCT core. Therefore, The present during the secondary winding is zero.
전류는 들어가고 나가는 전류의 크기는 동일합니다. 그러나 지락이 발생하면 전류가 정상적인
Non-intrusive installation: ZCT is typically put in across the neutral conductor of A 3-section program, which suggests that they may be put in without the need to have to break the circuit or interrupt electrical power on the load.
Though we have a three section program to shield, we only want one core in lieu of three if we use a CBCT or ZCT. This may be very practical for putting in and is simple.
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。
Current transformers are built to change large primary currents into workable secondary currents through a specified transformation ratio. For instance, a CT by using a four hundred/5 ratio can rework an true present of 400A down to 5A.
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。
The stage present-day from one among a few cables may have an unbalanced benefit. Therefore the zero sequence latest will happen from the secondary winding and circuit of CBCT.

This triggers a visit mechanism, effectively isolating the faulted part to circumvent damage and be certain basic safety.
The earthing potential customers within the cable sheath to earth and need to be taken from the eye this website on the ZCT Main. An average diagram is as proven within the beneath figure.
