Power quality interface for medium & high voltage networks

This is used to monitor quality of power delivered by utility and the quality of power received by user; to measure, monitor, control and record network electrical parameters and quantities; and generation of malfunction logs triggered by definable event. Recorder A can store sampling rates for time T1 (programmable). Recorder B stores half cycle values of T2 (programmable) seconds before and T3 (programmable) seconds afterwards. Recorder C records corresponding harmonic spectrum (10 minute values of 2nd .....40th harmonic), if the harmonic limit or THD (total harmonic distortion) of the voltage is exceeded. Other features: signalling of limit violation via LED or relay; compliant with defined limit values of DIN EN 50160; independent measurement U12, U23, U31, UNE; independent measurement I1, I2, I3, I0; sampling rate 10.24 kHz; 24 bit A/D conversion; acquisition of 3000 measurements; freely programmable limits and indication by voltage free contacts; 4 freely programmable LED indication; freely programmable digital inputs to start or to stop measurements; 8 measured quantities can be chosen and sent via mA signal as conventional transducer function; Win PQ software for user friendly data analysis supported by my SQL database; and serial communication port 2x RS 232 port, l x RS 485 port, E-LAN.
