Streaming Calculated Data Set.jpgI am doing  a proof of concept to demonstrate that PI Processbook can be used as a streaming data for any calculated values. In my graph , I created two calculated data sets.First data set is calculated secondary current. Then I use this value to calculate my next streaming data set which is the maximum short circuit value. My goal is to estimate the instantaneous fault current value reported by digital fault recorder (DFR) or SEL relay.
