Estudio sobre la medición de magnitudes eléctricas en circuitos de corriente directa y alterna.

Abstract

The lack of maintenance or a correct calibration in a measuring instrument can greatly affect the magnitude of an electrical measurement, for this reason it is of great importance for engineering training to have knowledge about the effects caused and the percentage of error caused by the problems mentioned above. In the present work, a mathematical analysis will be carried out on the impact that measurement instruments can cause in electrical circuits, this will be carried out by studying variables dependent on the connection, type of instrument and precision. Through this analysis, the degree of error caused in the magnitude of the electrical variables will be determined. The work is made up of three chapters, the first will be focused on the legal framework. The second is focused on the theoretical framework, in this chapter all the basic concepts that will allow us to understand the procedures carried out in the development of the work will be reflected. In the third chapter we can find the analysis corresponding to measurements, such as current, voltage, resistance and power measurements, both in single-phase and three-phase circuits.
