Abstract

On the methodological level, and also in measurement practice, significant errors have been noted in the measurement of electric quantities in distorted periodic systems, depending on the technological realization of the electronic measuring device or system. The paper describes a virtual instrument approach to the measurement of complex periodic electric signals, and particularly the power factor of "power saving" compact fluorescence bulbs. The analysis of the results also indicates that, in processing signals with a high harmonic distortion, it is necessary to pay attention not only to the measurement uncertainties but also to the dynamics of the measuring instruments that are used.
