PLC Studies in China as a Contribution to the Development of International Standards

In the field of PLC, the standardization process on international level is progressing very slowly. The EMC Laboratory of the North China Electric Power University has received the task to develop a measurement method for the field radiated by PLC installations and a standard to be used in the future for the regulation of the PLC deployment. After a short introduction of the standardization process at international level, the paper presents measurements performed at the North China Electric Power University of radiated fields due to PLC. Comparisons of the field with various limits are shown. Finally the paper also presents a review of the regulatory situation on international level
