Inductive coupler allows long-distance PLC

PREMO has developed a high current MV inductive coupler solution, MICU-300A OH/LF series, that it recommends for installations in outdoor bare overhead power lines as it offers insulation over 24kV. This compact, water-resistant (IP67) and weightless solution is compatible with mature and consolidated PRIME PLC standard and G3 popular standard, managed by the G3-PLC Alliance. The series supports CENELEC band (up to 150kHz) (Europe) and FCC (U.S.), which permits the use of frequencies less than 500kHz for narrow band PLC.

MICU-300A OH/LF series is made with high permeability and high performance materials that avoid saturation problems at high currents, allowing larger distances between pieces of PLC communication equipment located in different MV transformer stations. This helps to increase the broadband and to improve communication efficiency as it offers insertion losses of 12dB ±2dB (at 100-250kHz) and 5dB ±2dB (at 250-600kHz).  

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 and automatic meter recording. The series has been customised for Maxim G3 PLC modems and is also compatible with Enverv PLC modem Chipsets. PREMO offers evaluation kits to test this high reliability solution.
