Portable Three Phase Energy Consumption Acquisition System

Energy management becomes more and more important with respect to rapid increasing energy costs. Exact analysis of all installed electrical loads of a company is the basic requirement for starting and realising energy-saving measures. The proposed cost-effective mobile portable measuring system is composed of a standard notebook with PCMCIA slot, a data acquisition PCMCIA card and signal interfaces for current and voltage. We can measure (active) power of all power lines in an electrical distribution network regardless of voltage and current waveforms. Standard harmonics contents in current and voltage do not influence accuracy. All measured data will be saved on disk during the time of monitoring. These data can be analysed and interpreted easily using analysis software like DIAdem or simply EXCEL
