Diseño e implementación de una acometida para la máquina de prueba universal (TINIUS O OLSEN) del laboratorio de resistencia de materiales de la Universidad Técnica de Cotopaxi.

In the workshops of the Technical University of Cotopaxi, in the material strength laboratory, there is a TINIUS OLSEN universal testing machine that is powered by 220V triphasic that performs tests on different materials. This equipment came to have a serious damage in the control card of the machine system that caused its failure, this event was caused by not having an individual connection for its proper electrical supply, from this fact the measurement was taken into consideration and the analysis of the energy quality in the place where the equipment was energized, the objective was possible to fulfill since the University provided the measuring equipment called Fluke 435 energy analyzer, this has the capacity to measure any type of event that exists in an electrical network, for this reason it was installed in a hydropneumatic laboratory in the distribution sub-panel (TDS5) with the aim of being able to determine the voltage quality, this analysis was governed based on the technical requirements recommended by the manufacturer and IEEE1159, EN50160 standards and ARCONEL regulations. Thanks to these data, the voltage quality and events that could cause damage to it were evaluated, taking into account that the ARCONEL regulation has a minimum measurement time of 7 days in 10-minute intervals, for this reason it was considered to measure those of events that occur at that time, thanks to the POWER LOG 430-II software, the data could be extracted and the results were expressed through Excel, justifying in curves and percentages. The results are found in methodology, the design of a new connection was carried out considering the technical requirements, calculations and the norms that delimit the voltage ranges and dimensioning of the elements for the connection. It was considered to measure the new connection with the energy analyzer and as a result the voltage variation was improved without variations greater than 8% and with an average improvement in phase A of 1.38%, phase B of 2.79% and phase C0.93%. The voltage unbalance also improved since no measurement exceeded 1.5% unbalance and an improvement of 1.15% was obtained. These data are expressed within the analysis of results and are governed by the manufacturer's requirements, limits established by the norms and regulations already mentioned, this project was carried out successfully since the machine meets the connection, voltage ranges and adequate protections for the system.
