The paper considers the shortcomings of the existing regulations, governing the construction of the measuring equipment for the power quality conformity assessment by such parameter as the levels of the higher harmonic components. Providing the necessary power quality parameters is a prerequisite for the normal operation of a significant number of power consumers and the power supply system as a whole. The key element that allows to effectively regulate the relationships between the consumer and the supplier of power at the legislative level is a regulatory framework. One of the most important quality indicators are levels of higher harmonics in the current and voltage signals. The method, based on the discrete Fourier transform should be used as the main method for measuring the levels of the harmonic components of the current and voltage signals. The experimental data and their analysis, indicating the impossibility of A class assessment with a literal fulfillment of the standards were also given.
