unbalance protection meaning in English

不平衡防护

The protection system can deal with the following motor faults : heavy over - current , over / under - voltage , over - current , current unbalance protection , repeated startings , earth fault and so on
在此基础上实现了针对过载、堵转、短路、断相、逆相、相不平衡等故障的保护。
It has been verified by simulation tests that the symmetric short - circuit protection can not only avoid the starting current but also achieve higher sensibility ; unbalance protection can distinguish unbalance short - circuit and loss of phase . the operation parameters of other protective functions has all reached the design requirements
短路保护既能躲过起动电流，又有较高的灵敏度；不平衡保护，能准确区分不对称短路和断相故障；其它保护功能的动作指标均达到了设计要求。
