Measuring transducers MT 4xx

 

Summary

SR100 Supervision Relay is an intended to monitor and protect electrical equipment against common faults on Single-Phase or Three-Phase electrical power networks. SR100 is monitoring all important parameters of the electrical network in both directions (generator to consumer and vice versa) and detects potential faults in the electrical equipment and informs the user about them. For real-time communication CAN/CANOpen interface is build inside SR100 which transfers potential faults to the user system (SCADA, …) with milliseconds response resolution. SR100 is intended to protect the consumers on the electrical network against unattended faults which could occur (Undervoltage, Overvoltage, Underfrequency, Overfrequency, Asymmetry by Voltage, Asymetry by Phase, Imbalance, Load Overrun, Load Underrun, Phase Shift/ROCOF).
