earthed neutral system

基本解釋

Based on equivalent model of PT, this paper analyzes the reduced equivalent circuits to the power system with earthed and non-earthed neutral respectively.
分別對中性點(diǎn)直接接地系統(tǒng)和不直接接地系統(tǒng)的鉄磁諧振現(xiàn)象進(jìn)行分析，從理論上証明了PT的鉄損對鉄磁諧振的阻尼作用。
Distribution system are universally the non-solidly earthed networks, and the single-phase to earth fault happens most frequently in the power system with ungrounded neutral.
正確接地故障選線是小電流接地系統(tǒng)長期存在的難題，通常採用的單一故障選線方法衹對部分故障信息進(jìn)行処理，選線的可靠性不高。
In the article the author analysises and discusses earthed neutral system. Methods of electric resistance and autotracking arcextinguishing coil in neutral point are discussed.
本文就城網(wǎng)改造中，配電網(wǎng)中性點(diǎn)運(yùn)行方式問題進(jìn)行了分析、探討，強(qiáng)調(diào)採用中性點(diǎn)經(jīng)電阻和自動(dòng)跟蹤補(bǔ)償消弧線圈接地方式。
