Problem & Solution
HYPERSIM: End of acquisition POW not detected

Problem

I get this error on using ScopeView with HYPERSIM:

 " Error while data acquisition. Error while polling for the acquisition data. Error: End of acquisition POW not detected " 


Solution

One of the reasons that this error pops up is due to the incorrect configuration of the POW block. 

The first thing is to check all settings in the POW block, especially the detection level.

For example, consider the case when the detection level in POW block is set to 26kV and we get this error in ScopeView.



On examining the bus voltages to which the POW block is connected in our HYPERSIM model, we can see that they never actually reach the detection level of 26kV. 



Thus, the detection level is never crossed and so we get the error "End of acquisition POW not detected" in ScopeView.


On setting the detection level in POW block to a value such that the bus voltages cross it (i.e. < 26kV), we no longer get the error about the end of acquisition POW not being detected.





Note: The error "End of acquisition POW not detected" can also occur if the HYPERSIM model diverges (i.e. values are NaN) and thus we never cross the detection level specified in the POW block.
