permanent fault

This criterion uses the fault location result to get the fault point voltage and take the fault point voltage in theory as the setting value to distinguish the permanent fault from temporary fault.

该判据以故障点瞬时故障电压理论值为定值，由故障测距结果求出故障点实际电压，当故障点实际电压小于定值时为永久性故障，反之为瞬时性故障；

Research and Implementation about Permanent Fault Recovery Mechanism of a TMR Sever

一种TMR容错服务器永久故障恢复机制的研究与实现

A novel approach of distinguishing between temporary and permanent fault in single pole autoreclosing based on fault location is proposed.

该文提出一种基于故障测距的单相自动重合闸永久故障电压自适应补偿判据。

The results show that recovery voltage of temporary fault contains the components of power frequency component and free component, while the recovery voltage of permanent fault only contains power frequency component.

研究表明单相瞬时性故障时的恢复电压由自由分量与工频分量叠加而成，而永久性故障时的恢复电压中只包含工频分量。
