| Abstract: | With the wide use of electronic equipment and computers in secondary circuit of substations,the problem of electromagnetic interference(EMI) has become increasingly serious.This paper introduces the sources and transmission route of EMI in substation secondary circuit,the basic principle of anti-interference,and some safeguards in practice.The grounding method of cable shielding layer is also briefly described.Practice shows that adopting scientific and rational anti-interference measures can effectively protect secondary circuit from the influence of EMI. |
