The substation electromagnetic interference on secondary cable coupling into three categories

Starting from the concept of electromagnetic compatibility, on the main substation electromagnetic interference were classified, according to the object of study - disturbed secondary cable pathways and mechanisms are different, the secondary  mcb circuit breaker  electromagnetic interference coupled into three cables categories: conductive coupling, radiation coupling and the secondary circuit itself coupling; focuses on the FDTD method in the multi-conductor transmission line model in the application of the finite difference time domain method in a different multi-conductor  power transformers  connection in the case were computer simulation and explores the coupling law; the cables in the laboratory experiments, the finite difference time domain method validation, and a variety of interference signals on the cable interference generated by computer simulation
