Abstract: In article the analysis of the righteous character of loads in the measuring transformers of voltage in modern conditions. For example, the current waveforms of the secondary circuit TN to the existing substation is shown that the TN loads are becoming nonlinear in nature. The analysis of the amplitude and angular errors of instrument voltage transformers during their operation with nonlinear load. It is concluded that increasing of the total power consumed by nonlinear loads, an amplitude error of TN is not increased and is determined only by the power at the fundamental frequency. In this case, the angular error is determined by the level and composition of harmonics and may increase or decrease.

Key words: voltage transformer the amplitude error angular error non-linear load
