Analysis of cyclic DC load currents for intelligent electrical protection

Conceptual analysis of repetitive current of DC load is presented for two type of data processing approaches. Offline post-processing type approach as well as online adaptive data analysis method is introduced. Application of introduced analysis in case of repetitive DC current cycle with fixed duration is presented focusing of current-time behavioral investigation. Comparison of obtained analysis data and typical fuse character curve data is presented followed by brief discussion of prospective advantages.
