Errors in the measurement systems with the inclusion of single-phase loads at 220V in three-phase distribution networks

This research analyzes the problems presented by the measurement systems in one Phase three wires electrical distribution networks when single-phase loads are connected to 220V and proposes to replace the equation to eliminate the error that occurs in the energy meter. This case of study was given in Ecuador due to the massive inclusion of induction cookers through the change of the energy matrix promoted by the state since this account with more than 90 of hydroelectric energy to meet their electric demand. It is important to explain that this research does not include in the state of the art the problem and the solutions, because this novelty was presented promptly in Ecuador due to the technical conditions of the energy distribution system, at the voltage level versus the construction voltage of the single-phase loads that in the case of induction cookers were imported from countries that handle 220V single-phase voltages. This consequence does not present a choice, it is ethical for those responsible for the measurement systems of the Utility, to present a solution to the inconvenience of how it is developed in this investigation.
