Dalziel revisited 75 years later; analysis of mixed bipolar and monopolar waveforms

Abstract

Based upon his 1943 paper Professor Charles F Dalziel extended his Let-go effects analysis to mixed AC and DC waveforms plus various shaped nonsinusoidal waveforms to determine reasonable safe current limits feeling that it could be applied to any waveform. This paper revisits his analysis and extends it to modern non-sinusoidal waveforms to provide a substantiation for application of this analysis to nonsinusoidal touch currents found in modern electronic equipment.
