Software

SetPointPS software is a relay configuration tool for Bulletin 857 and 865 relays. The SetPointPS tool reads all information directly from the device, and it can be used to evaluate disturbance recordings from the relays. The built-in evaluator uses standard COMTRADE files for saving the records. SetPointPS is compatible with all Microsoft® Windows® systems (back to and including Windows 95).
