Energy quality in an operation center of data processings

The manipulation of the information through the use of computer science is the main responsible for the technological advance providing improvement in the quality of life. This provided to an increasing use of no linear loads in all sectors. Mainly, in the centers of network operation. The knowledge of the reply to these loads is important in the brainstorming that aims at the improvement of the energy quality. This paper presents measurements in common no linear loads in installations of a center of network operation. It analyses if the individual and total distortions of voltage are in accordance with Resolution 345/2008 of ANEEL.
