Methods of Evaluating Electromagnetic Compatibility of Cluster Electronic Equipments

The prediction of electromagnetic interference between the electronic equipments of a large information system is a complex problem. Furthermore, the prediction of the effect of interference on electromagnetic compatibility of the system is a random process, which causes much difficulty on practical application. Based on the results of electromagnetic interference analysis, three methods of evaluating the electromagnetic compatibility are presented. Evaluation model on certain electromagnetic environment is also discussed in this paper.
