Rapid Voltage Change values calculated as NaN/zero in DewesoftX 2025.3 Power module

Dear Dewesoft Support Team,

I have a set of three-phase current and voltage data acquired with SIRIUS. I want to calculate Rapid Voltage Change values (du(max), du(duration) and du(dc)) using the Power module. After configuring the setup according to the manual (see attached dwsX-01-manual.jpg; my configuration is shown in attached dwsX-01.jpg), I recalculated the data. However, the results for Du_dc, Du_max, and Du_duration are all zero (see attached dwsX-02.jpg).

Is this caused by incorrect settings on my part, or is it related to the software version? How can I fix it?

Software Version: DewesoftX 2025.3 (RELEASE[PWR]-260109, 64-bit)

Problem solved — after updating to the latest version DewesoftX 2026.1 (RELEASE-260225, 64-bit), the Du_dc, Du_max, and Du_duration values are now calculated correctly.

It seems the issue was due to the older software version.

Best regards,

Lucian
