New medium voltage inductive coupler for smart grids

PREMO MICU-300A-S/LF inductive cupler transmits the PLC signals between power line and PLC data transceiver without connection of communication cable to power line. This inductive coupler has a safer installation (High insulation > 5 kV) than a capacitive coupler.

A smart grid is an electrical grid that uses information and communications technology to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated fashion to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity.

One of the most robust standards in this technology, G3-PLC networking standard, supports high-speed and highly reliable IP-based communications across the existing power line, allowing data transmission, and distribution in the Smart Grid. Both capacitive and, easier to deploy, inductive couplers are used as interface between data equipments and powerlines.

The new PREMO MICU-300A, is a high current solution made with high permeability and high performance nanocrystalline materials which avoid saturation problems at high currents. Moreover, it offers low insertion losses, 8dB±2dB (@100-250kHz) ; 5dB±2dB (@250-600kHz).
