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.
分別對中性點直接接地系統(tǒng)和不直接接地系統(tǒng)的鐵磁諧振現(xiàn)象進行分析，從理論上證明了PT的鐵損對鐵磁諧振的阻尼作用。
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，通常采用的單一故障選線方法只對部分故障信息進行處理，選線的可靠性不高。
