Mediçâo de energia da universidade federal de lavras através do software livre mrtg

Abstract

The objective of this work consists of making the adaptation of free software MRTG to make the generation of graphs of as it is being the consumption of electric energy of the departments of the Federal University of Lavras. For the acquisition of the data of the electric net a measurer of the Yokogawa company was used who has the function to read the eletric power of the net, and to make avaiable these data in the analogical form. Of ownership of these analogical data was constructed a converter A/D (Analogical/Digital) that it has the function to transform that analogical signal into digital signals, that will be used for the MRTG for the generation of graphs of the electric consumption of the place.
