UNWANTED SPIKES IN PSO2020 TREND AND ADVANCE REPORTING.

[kishore1march]

Dear Guide, 

I am experiencing a sudden spike for a period of 1 to 5 minutes in the scada graphics, trends and advanced reporting for some of the PMU meters. I am not sure theses spike are generating from PMU or by SCADA itself?. Eventually it is affecting our advance reporting calculations.

Can someone please support me, how to combact the recording the sudden spike data in trends and advanced reporting?
