Abstract
Fast development of various types of converters makes their utilization in industry and in domestic installations very common. Due to converters, an earth fault current waveform in modern circuits can be distorted or its frequency can be different than 50/60 Hz. Frequency of earth fault (residual) current influences tripping of residual current devices which are widely used in low voltage systems. This paper presents the behaviour of residual current devices when residual current of frequency lower than 50 Hz flows. The results of the analysis have shown that many of commonly used residual current devices are not able to detect residual current when its frequency is significantly lower than 50 Hz. Thus, protection against electric shock may not be effective.
