A recent transformer is used to phase up or stage down alternating recent, where CBCT or zero sequencer is applied as fault protection.

In this manner, we is not going to uncover any remainder of zero sequence present from the CBCT Main winding. As it can be a well balanced three period, there will not be any flux created during the CBCT Main. Hence, The existing in the secondary winding is zero.

Due to this fact, the CBCT’s secondary-connected earth fault relay will develop into activated, isolating the health and fitness system with a circuit breaker.

Detection of unbalanced recent: ZCT is created to evaluate the unbalanced recent in A 3-stage electrical procedure, that's the sum of the 3 period currents.

　零相変流器の２次側に保護継電器を設置しておき、電流が流れたら遮断器を開放するようにしておけば地絡事故発生した場合に迅速に故障箇所を電気回路から切り離すことができます。これが零相変流器の設置目的と使用法です。

Variety of CBCT or ZCT The following conditions are accustomed to choose the ideal zero sequence CT or CBCT. Nominal CT ratio: This could be set to ensure, even in the case of a small ground more info fault, There may be plenty of present-day to run an earth fault relay.

The resultant flux is zero (Φr = 0). What this means is there isn't a present flowing from the secondary circuit of our CBCT. Its earth fault relay gained’t get operated since it is a ordinary operation.

高卒で電験１種に奇跡の合格ができた管理人が電気系資格の情報や突破対策を発信。

Due to this fact, the magnetic flux necessary to produce a particular secondary present is lowered to 1-third (one/3), which happens to be the best gain supplied the improved Over-all sensitivity in the protecting procedure.
