Abstract:This paper analyzes the breaker three-phase trip caused by of non-full phase protection action of breaker reality for single-phase grounding in 220 kV lines.According to this example, some measures about the relay pertinent circuit of non-full phase protection action of breaker reality are proposed.Relaying protection personnel must attach importance to non-full phase protection and improve the reliability of non-full phase protection. The security and stability of power line are enhanced.
Keywords:non-full phase protection  single-phase grounding  reliability
