请教几个专业英文

首先这个不知是不是输入缺相
　　supply loss: one or more of the power(input) supply phases is open-circuit.
　　而这两个又是什么呢？
　　power supply: one or more of the intemal power supplies is out of tolerance.
　　phase seqvence: connections to E1 and E3 are not the same phases as are connected to L1 and L3 investigate and correct.

是；电压超出范围；相序（你好象拼错了）故障。

supply loss: one or more of the power(input) supply phases is open-circuit
　　电源缺相：一相或多相电源输入端开路中（即无电压）power supply: one or more of the intemal power supplies is out of tolerance.
　　　　电源（问题）：电源输入端的一相或多相不在正常范围内（电压不正常）
　　phase seqvence: connections to E1 and E3 are not the same phases as are connected to L1 and L3 investigate and correct
　　相序问题：E1和E3的相序连接与L1和L3的连接相序不一样或不正确
　　

感谢二位的热心帮助！！！
