Medium Voltage Systems

The Gridline medium voltage system allows delivery over a much wider Metropolitan Service Area (MSA) more efficiently, so as to reach a larger number of customers, thereby providing a greater and more rapid penetration rate. The Gridline medium voltage system differs from the low voltage configuration in that it requires significantly more hardware than the low voltage system. The hardware responsible for taking broadband signals from the PLC Mid Voltage Coupler to the PLC Gateway Router in this configuration is the PLC Medium Voltage Bridge. This insulation resistant device supports the local PLC Gateway Router. The PLC Medium Voltage Repeater in this configuration relays frames between the PLC Medium Voltage Bridge and the Bridge Slave via 22kV or 35kV power line. It is relatively easy to install, and automatically detects existing PLC devices. The PLC Medium Voltage Slave gets broadband signals from the PLC Mid Voltage Bridge or the Repeater, and passes the signals to the PLC Gateway Router. A Medium Voltage Coupler superimposes broadband signals into the 22kV or 35kV power line utilizing a frequency range specification between 1 MHz to 30 MHz, with a very low signal loss of about 3dB.
