Monitoring and evaluation of the quality of electricity in a building

Abstract

The term, “Quality of Electricity” has been applied to a wide variety of many power system phenomena. The increasing application of electronic devices as well as the production and distribution of electricity has increased the interest in energy quality. Today, non-linear loads have increased, mainly with the addition of computer equipment, printers, photocopiers, fans, heaters, air-conditioning systems, refrigerators, elevators, etc. Therefore, it is good to take some measures to reduce the levels of general disturbances, as well as to immunize the sensitive equipment in such a way as to ensure the stability of the electrical installations. To achieve these objectives, it is important to measure and analyze harmonic distortion. For this, the origins and possible consequences of harmonic disturbances in computer equipment and distribution networks of the building or university campus are studied, which is the focus of this study. The paper argues the main precision strategies in an electrical installation applied in a building, in which the biggest loads are computer and laboratory equipment. For this and many other reasons that affect the Quality of Electricity will be argued.
