Quality Of The Electric Power Under The Perspective Of The Systems Of Earthing

The quality of energy depends on the normal conditions of operation of the electrical systems as for stability (voltage and frequency), distortion of the signs and the continuity of the service. High places assure quality levels it needs of the study of the influence of the suitable hookup of the systems of earthing, along the whole chain of value (generation, transmission, distribution), under the perspective of his contribution in the stability, decrease of disturbances and interruptions of the electrical service. In this order of ideas, in the present work there are realized a bibliographical review centred on theories and scientific investigations of the best practices for the design, construction and maintenance of the systems of earthing, complementing itself with an exploratory analysis of the historical information of a particular case of the electrical Venezuelan system, where there is demonstrated that about 30% of the problems of interruptions and disturbances in the lines of transmission are a product of the high resistances in the systems of earthing or for the lack of continuity between the protection systems against atmospheric unloads
