the aim of research is to explore the methods of electrical power measuring in to non-sinusoidal AC circuits especially Fast Fourier transformations (FFT) based. The FFT method can be used for measuring AC electrical power for any device, signal or system in order to get a more detailed power spectrum and its harmonic division, which would help analyse the work of the electrical equipment or system and optimise the energy used. In comparison to the standard electrical power measuring method there is a small but constant change in the measurements gained, that with high electrical energy consumption could make a significant difference. Investigation of influence of FFT bin precision to mains frequency also was performed. A micro-controller based device was developed in order to perform such tests.
