In this research are presented the results of the measurements of the electrical parameters obtained by the three phase analyzer of electrical energy, there was used a methodology based on the own manual of the analyzer equipment, well as the national and international standards as well the IEEE Institute, the CFE company, and books of the subject, in which are stablished the limits and requirements for a good quality of the electrical energy necessary for the user of the electrical service. The contribution covers from the conection of the entry of the analyzer equipment until the instalation to the exit of low tension in the transformer, verifying in the equipment the vectorial diagrams and senoidals for corroborate that their conection be adequate, also were considered the measurements of the security in the instalation of the measurement equipment, throughout the document are mentioned the characteristics and the interpretation of each electrical parameter analyzed.
