Software tool for visualizing IEC 61850 Sampled Values

SVScout is a measurement and testing tool for protection engineers and IED developers working with IEC 61850 Sampled Values. SVScout subscribes to the Sampled Values streams from one or multiple merging units and displays the waveforms of the primary voltages and currents in an oscilloscope view. SVScout supports Sampled Values according to the implementation guideline of the UCA International Users Group with 80 or 256 samples per cycle as well as DataSets recommended in IEC 61869-9.

The functionality of SVScout covers many different tasks reaching from the simple display of Sampled Values streams to the detailed investigation of a merging unit's performance. For example, the software can be used for commissioning or for testing and developing of merging units.
