| Abstract: | The HF blocking protection is composed of WXH -11 and SF - 500 transceiver. If the HF blocking zero sequence protection mal-operates without blocking at external forward fault, it maybe the cause of interference and cooperation between microcomputer proteetion and transceiver. The paper analyzes the cooperation problem between microcomputer protection and transceiver. |

| Keywords: | microcomputer protection HF blocking zero sequence protection cooperation sequence |
