| Abstract: |
| Based on the internal fault of a motor,the in area fault sensitivity is increased to response the slight fault type while the effective measures are taken to prevent the out area fault malfunction. It offers a real effective protection for motor. |
| Key words: positive, negative, zero sequence current,absolute selectivity,motor protection relay, |
