O.K. - to satisfy you and others with measurements results I will measure the mains disturbances before the power supply and after. I have access to necessary tools. The problem is to find the time. I do not really know when I will be able to conduct the tests. Waiting for this I am available for the discussion.

Hello
That you have access to the proper and necessary tools is good. I would like to see the results as well. Looking forward to your spectrum analyzer results. I will be particularly interested in the harmonic range and levels this interference is occurring at.

The only problem I have is to get suitable current probe as the one we normally use is to measure emissions on large power cabling. I will need to fiddle a bit with the board's supply cabling. This is the only thing which pushed me away from conducting the tests to date.

Hello
A current probe is not used with a spectrum analyzer so is not needed for proper troubleshooting of EMI emissions/interference. I'm not sure what testing you would be performing with a current probe but it will be irrelevant to the problem creating the issue you are claiming.
