求翻译：Normally, the phase current criterion and current-zero criterion are the cause, which will pickup CB fail protection. When the generator-transformer unit is running with non-three-phase during starting and shut-down, the phase current is very little and it can’t pickup CB fail protection, which will damaged generator. 是什么意思？ 待解决
