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(duì)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(duì)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.
