Power line communications (PLC) is a global technology that is gaining interest worldwide due to the wide availability of power distribution lines. In smart grids inductive couplers are playing a big role as it transmits the communication signals between power line and PLC data transceiver without introducing any new wires or cables; being a competitive solution compared with capacitive coupling. PREMO has developed a new high-current medium-voltage (MV) inductive coupler solution, the MICU-300A OH/LF series, that is recommended for installations in outdoor bare overhead power lines as it offers insulation greater than 24kV.
This compact, water-resistant (IP67) and weightless solution is fully compatible with mature and consolidated PRIME PLC standard and G3 popular standard, managed by the G3-PLC Alliance. The new series supports CENELEC band (up to 150 kHz) (Europe) and FCC (U.S.), which permits the use of frequencies less than 500 kHz for narrow band PLC.
MICU-300A OH/LF is an easy-to-install solution with waterproof (IP67) connector integrated in the coupler that helps to save time during installation. Other connections are available under request. By means of using this non-intrusive solution, blackout or grid disconnections are avoided.
MICU-300A OH/LF cost-effective solution is suitable for applications like automation of electric power distribution system, power line monitoring system, automatic meter reading), etc. The series has been customized for Maxim G3 PLC modems and is also compatible with Enverv PLC modem Chipsets.
