Andurist AC lugemine

Üldiselt on softiga tegemisel mõte, AGA:

1) Sämpli vähemalt 10kHz sagedusega
2) Lisa enne ADC Besseli madalpääsfilter 1kHz lõikesagedusega (ei ole nii hull kui kõlab, veebis on kalkulaatorid olemas), kusjuures vaata et pingel ja voolul oleksid samad filtrid, muidu tekivad faasivead
3) Softis pead tegema kaks asja:

a) korruta pinge ja voolu hetkväärtused ja võta RMS
b) arvuta pinge ja voolu RMS ja korruta

Nii saad nii näivvõimsuse kui aktiivvõimsuse ja boonusena võid arvutada ka cosfi.
