Line-To-Line Voltage Line-to-line voltage is the voltage between any two phases of an AC generator. 线电压线电压是指交流发电机任何两相间的电压。
Fault Phase Selector for HV Transmission Line Protective Relaying Based on the Characteristic of the Arc Voltage Between Two Faulted Phases 基于相间故障弧光电压特征的高压线路选相元件
The integrating criterion for distinguishing permanent or instantaneous fault condition is put forward using voltage amplitude of fault-phase, phase relationship of voltages between fault line and no-fault lines, and harmonic of fault phases voltage. 提出采用故障相电压幅值大小,故障相电压与非故障线路电压之间的相位比较,以及故障相电压谐波大小的综合判据,以区分永久性故障与瞬时性故障,实现有选择的单相自动重合闸。
The results show that: ( 1) the zero-sequence current but not the voltage can be detected by the protections located at both sides of transmission lines during overhead line fault between different phases; 结果表明,异名相跨线故障期间,各端保护可以检测到零序电流,但无零序电压;
Further analysis of single-phase ground fault other than the failure of the formation process, and the failure process of voltage and current wave recording records and found that most of the short circuit between phases is also due to the initial single-phase ground fault evolved. 进一步分析单相接地故障以外的故障的形成过程,以及故障过程中电压、电流的录波记录,发现大多数相间短路也是由于最初的单相接地故障发展而来的。
