Adjusting sampling rate of PMU data

Jul 6, 2012 at 1:42 AM

Hi All,

we have PMU with sampling rate of 50 per second. I have installed openPDC and its work properly, but Historian just shows maximum 25 samples per seconds.

Even when I change the sampling rate to 50 in "Device" properties dialog box, the Historian just shows 25 samples.

Could you please help me on this matter?


Thanks in advance

Not sure of the issue here - when you say the Historian just shows 25 samples, is this based on a query from the historian?

Dear ritchie,


overall, although I set the sampling rate to 50, the data which is obtain from historian is 25 sample per second. or when I capture data from connection tester, it shows 25 samples per second. How I can change it to have 50 samples per second?


Best regards
