Metrological analysis of an computerized system of protection against electric shock in circuits with variable speed drives
Abstract
Drive systems, that can be operated at variable speed, are equipped with power electronics converters. This causes distortion of the earth current, and consequently the need to take into account the use of proper protective devices in relation to earth current harmonics. This paper presents a system for protection against electric shock in circuits with power electronics converters and metrological analysis indicating the requirements for the present measurements for this purpose. The reasons for errors in rms current measurement have also been presented in this paper.
