PLC’S:PLC’S:
Power Lines, originally devised to transmit Power Lines, originally devised to transmit electricityelectricity from some sources to many from some sources to many sinkssinks
Power Lines can be used for transmission of Power Lines can be used for transmission of power as well as communication i.e., data is power as well as communication i.e., data is modulated on a carrier frequency and sent modulated on a carrier frequency and sent over over

AMR-important application as every user AMR-important application as every user connected each other via power lines. In connected each other via power lines. In this power network, every user connected this power network, every user connected to each other via modems with data to each other via modems with data originating from the remote meter or originating from the remote meter or central station central station
Detection and Control SystemDetection and Control System
Schematic illustration of detection system of illegal electricity usage
PLC signaling is only valid over the low voltage VAC power lines
PLC signaling must be in CENELEC standards
PLC1A….PLCNA are PLC Modems and used for AMR (Subscribers Location)
PLC1B….PLCNB are Energy Meter Chips of detector (Connection Points)
Detection and Control System Detection and Control System (contd…..)(contd…..)
Schematic illustration of detection system of illegal electricity usage
Proposed detector system has two recorded energy data in host PLC unit, one, which comes from the AMR-PLC, and the other, which comes from the PLC modem at the connection points
An Error s/g is generated indicating illegal load Usage
