健全な電路では零相変流器の二次側は電流が平衡しており流れることがないが、三相を一括で通した電路に地絡が発生した場合、零相変流器に流れる電流のバランスが崩れ、二次側に電流が発生する。発生した電流バランスの崩れを検出するのが零相変流器の役割である。零相変流器の二次側には地絡継電器などの保護装置が設置され、故障電流の検出といった電路保護に使用される。

A recent transformer is utilized to move up or step down alternating existing, wherever CBCT or zero sequencer is utilized as fault safety.
新エネルギー発電の知識 新エネルギーとして代表的な太陽光発電、風力発電、燃料電池や、排熱再利用など。
Due to this fact, the CBCT’s secondary-linked earth fault relay will turn out to be activated, isolating the wellbeing procedure which has a circuit breaker.
省エネルギーと脱炭素 カーボンニュートラルを達成し、二酸化炭素の排出を削減と吸収の技術について解説。
In distinction to your current transformer (CT), a click here CBCT’s Major winding is crafted from A 3-Main cable that operates through the center of its iron core, and its secondary coil is wrapped on a ring-shaped iron core that is certainly associated with an earth fault relay.
As a result, no flux will emerge in the Core of CBCT. As a result, the secondary circuit with the CBCT will likely be wholly static.
Can it be residual stage input or separate CT enter. The "ZCT" or residual will often begin to see the imbalance together with the section to ground fault latest, but This really is also imbalance.
電線・ケーブルの種類 電力ケーブル、通信ケーブル、光ファイバーなど数多く存在するケーブルの特徴を解説。
The installation of the proper type of CT based on the precise security demands as well as the program’s operational qualities can appreciably enrich process trustworthiness and basic safety.
