Current spikes of 242A and energy windows not plotted #53

Open tobyaharris opened 1 day ago

tobyaharris commented 1 day ago

Just checked the dashboard of our demonstrator for advanced power monitoring 3 phase this morning. The clamps are 60A/5A CTs and are configured as such on the MFM. The last 6 hours look like this: image Besides the test between 11:40 and 11:56, all non-zero data points appear to be spurious noise. Zooming into the first of those green spikes at 0751: image It's a single reading of an impossible level of current.

These usually follow a data dropout. Perhaps caused by data collection restarting? The other spikes peak to different values (122A / 120A also observed)

The engery spike becomes a more sensible box if the time bucket is reduced: image but why is the box of the same height not drawn at the 1hr bucket size? Zoom in on it as it is and the spike dissapears.

What do the log files say for that period? is that the value that was reported by the MFM or has something happened post sample?

do show a reading of 241.73A just on phase A, but with no power.

This is on the first sample after recovering from #43 .
