ABSTRACT-- Power line communication (PLC) presents an interesting and economical solution for Automatic Meter Reading (AMR). If an AMR system via PLC is set in a power delivery system, a detection system for illegal electricity usage may be easily added in the existing PLC network. In the detection system, the second digitally energy meter chip is used and the value of energy is stored.
The recorded energy is compared with the value at the main kilo Watt-hour meter. In the case of the difference between two recorded energy data, an error signal is generated and transmitted via PLC network. The detector and control system is proposed. The architecture of the system and their critical components are given. The measurement results are given.
This paper describes detector system for illegal electricity usage using the power lines based on the research work-taking place at the Central Power Research Institute (CPRI), Bangalore. The target of this study is to discover new and possible solutions for this problem.
