摘要
本文对电力线通信(PLC)系统的电磁辐射进行了分析。利用实验获得的不同典型室内配置的耦合因子,我们计算了具有EN550022/CISPR22限值给出的幅度的信号相关的辐射场。我们表明,在很宽的频率范围内,产生的场超过了目前的一些排放限制,如德国的NB30,英国广播公司,挪威和英国的MPT 1570提案。另一方面,这些领域仍然在外推的EN 55022 B类和FCC Part 15的限制范围内
Evaluation of indoor PLC radiation resulting from conducted emission limits
We present in this paper an analysis of the electromagnetic emission associated with power line communications (PLC) systems. Using coupling factors obtained experimentally for different typical indoor configurations, we calculate radiated fields associated with signals having a magnitude given by the EN550022/CISPR22 limits. We show that the resulting fields exceed, for a wide range of frequency, some of the current emission limits such as the German NB30, the BBC, the Norway and the UK MPT 1570 proposals. On the other hand, the fields remain within the limits of the extrapolated EN 55022 Class B and FCC Part 15
