In OpenPDC I applied a correction of ‘-120’ to certain phase angles. After initialing the PDC and its equivalent in OpenHistorian (STTP connection between the two); I note that this modifier is not automatically included / replicated in the measures of OpenHistorian. Should I report the same change in OpenHistorian to keep consistency; or is the fact of applying it once in OpenPDC enough to correct the signal on the whole downstream chain? I do not want to have a (-120) + (-120) = (-240) correction on my OpenHistorian data … As it’s phase angle ; it is difficult to compare directly OpenPDC/OpenHistorian values at a specific time using the Monitoring > Graph Measurement tool because values are changing quick …
I think I have to do it on OpenPDC only ; but I prefer to have your confirmation !
Thank you very much for your answer
