| Abstract: | When a high-power electric motor is starting,the current is heavy and the traditional protection strategy can't distinguish if it is a short-circuit current or the normal starting current,so the system is tend to make wrong.The paper introduced a kind of high performance protection strategy about electric motor starting—phase-sensitive protection and the realized process according to SPCE061A chip. |
