TIEVM-VIENNARECT: three-phase Vienna：VIENNA_iL1MeasOffset_pu

Libra_V

Through theoretical analysis and experimental verification, I found that Vienna_ iL1MeasOffset_ Pu= 0.5, and obtained X through certain calculation, (I don't quite understand the calculation of the deviation)

So I have a new idea, whether we can define Vienna_ iL1MeasOffset_ Pu = 0.5 in the main function instead of calculating the deviation.

The details are as follows:

Change the VIENNA_iL1MeasOffset_pu in the red box to 0.5：

I don't know if this idea is right. Can you do an experiment to verify it？

thanks

Hi,

This calibration method is applied for different boards so theoretically you are not suggested to use a fixed value. But surely you could change it for your specific test.

Can you use the three-phase Vienna board to test it? I'm afraid that when I test the circuit board, it will be very troublesome for the after-sales maintenance.

Hi,

We will not be able to conduct this kind of test since this is beyond our test spec. You could make sure the protection is working before doing this test. But yes, you need to consider the risk as well.

Chen
