Abstract
This paper presents a virtual measurement apparatus used for active power measurement. The apparatus use, for the values of measured voltage and current sampling a data acquisition device such as PCI/LPM/16 made by National Instrument. The apparatus is an LABVIEW programming environment application. The main advantage of this apparatus is than is possible to be measured with some precision both sine wave and not sine-wave signals power.
