Abstract:
1. An apparatus for remote multi-channel metering of electricity using power line communication, comprising: a plurality of metering points located on a secondary side of a transformer and operable to separately measure electricity usage for each of a plurality of electricity consumer lines; said apparatus in direct communication with a transponder located on a primary side of said transformer operable to transmit data to and receive data from said transponder via direct power line communication, said transponder operable to transmit data to and receive data from a remotely located computer; said apparatus operable to control one or more load control modules operable to actuate connection and disconnection of each of a plurality of relays, each relay of said plurality of relays corresponding to one of said plurality of electricity consumer lines; and a box containing said plurality of metering points, said load control module, and said relays, wherein said distribution transformer converts medium tension distribution voltages to low tension voltages appropriate for supplying power to customers, and wherein said apparatus is operable to inject signals onto and receive signals from low voltage power lines that supply customers with electric power; said signals providing two-way communication between said meter head and said transponder and traversing said distribution transformer.
