I’m developing an application similar to a 3 phase e-meter application using Rogowski coils.
I’m using TI provided library softdidt for IAR and MSP430F6779A.
I have a custom pcb based on TI designs.
In the attached file you can see some samples I stored and the graphs generated.
I saved the didt, the vt, ifiltered and vfiltered for a 230V, 6A, 0º load.
The Rogowski output lags 90º from the system current and after integration lags another 90º, making the ifiltered 180º from system current. This is the Rogowski working principle as my understanding.
My understanding is that my system should compensate for all this 180º delay, right? So my ifiltered should be in phase with vfiltered and not 180º apart. Is my assumption correct?
