Remote oscillography gives network visibility

Distribution network protection assets such as automatic circuit reclosers provide a grid wide view of a system, but network monitoring by means of conventional SCADA is no longer sufficient with increasing load complexity and distributed generation. To assist engineers, Noja Power’s OSM recloser provides a platform for oscillography capture and remote transfer of these sample files back to the control centre of the network. Oscillography files are captured in industry standard Comtrade format, allowing utility engineers to analyse the current and voltage waveforms throughout the network. When combined with traditional analysis methods, this empirical data allows many benefits, including: improved accuracy of network modelling; detecting  harmonic/power quality issues prior to equipment failure; and fault location information.
