If you have distorted currents and voltages, you need to do this. 3.6kHz sampling captures harmonics up to 1.8kHz, which is the 36th harmonic. Power is 1/T \int

If you have distorted currents and voltages, you need to do this. 3.6kHz sampling captures harmonics up to 1.8kHz, which is the 36th harmonic.
Power is 1/T \int_0^T U(t)*I(t)dt for periodic signals with period T, and if current and voltage cannot be assumed to be sinusoidal, faster sampling is needed.
