Power-line-comms coupler links signals frompower line to data transceiver

May 27, 2013 // By Julien Happich
Premo has launched a waterproof kit including two units of its medium voltage non-intrusive inductive couplers for smart grids. The MICU 300A-S/LF inductive coupler transmits the PLC signals between power line and PLC data transceiver without connection of communication cable to power line.

With a rated insulation greater than 5kV, this inductive coupler offers a safer installation than a capacitive coupler. Very fast to install and featuring a very low attenuation at low frequency, this high-current solution is suitable for cabinets and underground power lines. The inductive couplers use high permeability and high performance nanocrystalline materials which avoid saturation problems at high currents. Insertion losses are 10 dB ±2dB from 100 to 250 kHz, and 5dB ±2dB from 250 to 600 kHz. It offers an optimum performance at 500kbit for PRIME PLC Smart grids solutions.
