Abstract: Intelligent assembly is the key to the intelligence of power equipment, but there are many factors including extremely
complex environment, various sources of electromagnetic disturbance and poor electromagnetic environment hampering the running
of the assembly. To improve the reliability of the intelligent assembly, it is particularly important to solve the problem of electromagnetic
compatibility. Though the characteristics analysis of electromagnetic disturbance sources of gas insulated substations and
its coupling paths, this paper studied the inhibiting effect of shunt capacitor and ferrite bead on electromagnetic disturbance and
carried out tests for verification. Experimental results showed that those methods can effectively restrain the influence of disturbance
voltage on intelligent assembly, providing the basis for the design of electromagnetic compatibility. Key words: gas insulated substations; intelligent assembly; electromagnetic compatibility; suppression measures
