Abstract: The paper deals with power quality in industry and in households. A new virtual instrument-power meter and power quality analyser is described. The instrument enables complete monitoring of all the powers and power quality parameters, as well as simultaneous measurements of voltages and currents and application for motor current signature analysis (MCSA) and technical diagnostics. The results of measurements in different industrial plants and in the households are shown and the influence on the power quality is evaluated and discussed. The complete and continual measurements of the powers and power quality characteristics give basis for technical diagnostics and for consideration of the technical and economical aspects of energy policy, planning and contracting of the electrical power.
