Test and study of impact of electrified railway on audio-video program production
Through testing and analyzing the impact caused by the electrified railway on audio-video program production, this paper indicates that the electrified railway will cause obvious impact on the audio-video system, especially the audio frequency, within a certain distance. The interference is mainly electromagnetic radiation coupling interference. Under the condition of bad earthing, static induction impact will also become an interference source not to be ignored. The protective measures should be laid particular emphasis on increasing the balance level of the audio-frequency transmission line, improving the earthing effect or implementing the electromagnetic screening measures.
