zero-phase sequence currentとは 意味・読み方・使い方

A screen-shaped shielding wall to partition a space in the inside of the case into spaces on the power supply side and on the load side by interposing it between the overcurrent trip device in each phase and the zero-phase sequence current transformer standing side by side behind it, is provided in the inside of the molded case.例文帳に追加

モールドケースの内部に、各相の過電流引外し装置とその背後に並ぶ零相変流器との間に介装してケース内部の空間を電源側と負荷側に仕切る衝立状の遮蔽壁１６を設けた。 - 特許庁

Consequently, the zero-phase-sequence current transformer ZCT detects an unbalance of a combined current of the currents in the feed paths L1, L2 and the branch paths L5, and thereby can correctly detect a leakage.例文帳に追加

これにより、零相変流器ＺＣＴは、給電路Ｌ１，Ｌ２と分岐路Ｌ５の合成電流の不平衡を検出することになるので、正確に漏電を検知することができる。 - 特許庁
