Re: PicoScope 4424 Phase Angle Measurements

Active power P=U rms *I rms *cosφ Power factor cosφ=integral(A*B)/(sqrt(integral(A*A))*sqrt(integral(B*B))) φ=acos(integral(A*B)/(sqrt(integral(A*A))*sqrt(integral(B*B)))) [rad] φ=acos(integral(A*B)/(sqrt(integral(A*A))*sqrt(integral(B*B))))/Pi*180 [deg] I have in mind this phase angle. Measurement ...
