Thanks to PLC communication technology, overhead and underground distribution networks can be transformed into broadband telecom networks, thus adapting to the most advanced needs of the smart gridArteche has wide-reaching experience in the design and manufacture of PLC couplers for medium voltage distribution automation. In recent years, it has installed close to 30,000 PLC couplers in 22 different countries. In this way, it has contributed to improving the quality of electricity supply in distribution networks in Europe, North America, South America, and Asia. Our expert engineer Aurelio Gámez will present our knowledge about PLC couplers and their design. He will do so at the 20th edition of the 2019 Electricon expo, the meeting point for leaders in the electricity market, which will be held from October 23-25 in Guadalajara, Mexico. On the 25th, he will present the paper “Success Stories with PLC communication technology for overhead and underground distribution networks” in the Innovation room from 3:00 pm to 4:00 pm. Communication over power lines is regulated according to IEEE P1901 and ITU-T standards, with PLC technology being the only technology that offers a lower price point in terms of infrastructure due to the fact that distribution lines are already available. In this manner, we continue to actively participate at this benchmark conference for the electrical sector in Mexico. In 2018 we presented our knowledge on reclosers and their design for Smart Power Grids.
