Abstract


Rising energy costs, a green image and fulfilling of political demands are some reasons, why companies try to reduce their energy consumption. Biggest challenge is to identify potentials, derive measures and realize them. Although, measuring instruments are available in a great variety there exists no cheap and flexible system, which uses the measured line for supply and data transmission. This innovation, introduced in this paper, delivers a new possibility for post-crosslinking and smart energy monitoring. Based on current powerlinecommunication (PLC) technologies and modulation methods, a hardware was developed. A program handles the PLC and manages the measuring. The system has sensors for alternating voltage and current and calculates frequency, power factor, active, reactive and apparent power. For visualization and further analysis, a software was established. The complete system was evaluated in a production facility. The accuracy shows a difference of 1.5 % to a reference.
