Disturbance recorder RZS-9

The disturbance recorder type RZS-9 is a priceless tool for analysing causes of power system faults. It memorizes values of currents and voltages as well as statuses of binary signals coming in from the switchgear, during time of the fault. It enables checking the working conditions from before and after the end of the fault, including correctness of operation of protections. The software, delivered along with the device enables precise analysis of all registered curves.
