In HV transmission lines, the existence of large fault resistance may easily result in tripping missing or maloperation of distance protection. 摘要高壓輸電線(xiàn)路中存在較大的過(guò)渡電阻，很容易引起距離保護拒動(dòng)或誤動(dòng)。
With the results the article describes the advantage and importance of microprocessor-based phase spacing protection used as far-ranging back-up relaying of adjacent devices. 通過(guò)計算分析剖析了微機相間距離保護用作相鄰元件后備保護的優(yōu)越性及重要性。
