On medium voltage power lines Broadband Powerline (BPL) Communications offer a cost-effective platforms for smart grids. Using the existing infrastructure, and with the minimum of operational disruption, BPL devices can be installed everywhere on the medium voltage grid to provide secure, reliable data communications for smart grid operations and application.
Until recently, powerline communications on overhead lines was limited to narrow (PLC) bandwidths, only capable of intermittent data transmissions. PPC has developed an outdoor IP67 coupling solution that enables continuous broadband data transfer; bi-directional and in real time on overhead lines of 12kV and 24kV.
Built to withstand the rough conditions of the overhead network, the MV coupling solution is deployed in the field already in three countries achieving broadband data transfer distances many times further than was previously possible, up to 4km, and even further with repeating.
PPC’s capacitive couplers have been developed for the transmission of broadband signals over 12 kV and 24 kV networks, connecting the electricity grid with BPL modems.
Their compact design makes them ideal for use underground, in compact gas and air-insulated switchgears and in substations where space is limited.
