| Abstract: | This paper analyzes the main source of interference in secondary circuit and the influence on the microcomputer based protection in substation. Measures of anti_interference in substation is given, which include using the shielded cable correctly, arranging ground connection into equal electric potential, improving the high frequency channel, the secondary circuit of CT and PT has only one ground point respectively. The secondary circuit and the third circuit are mutually independent. For safe operation in microcomputer protection, it is important to put these anti_interference measures into practice. |
