Programación e Implementación de Interfaz Gráfica Aplicada al Osciloscopio Tektronix dpo 7054c para Pruebas Tipo Impulso en el Laboratorio de Alta Tensión de la Universidad Distrital Francisco José de Caldas

Abstract

At the Universidad Distrital FJDC, a digital phosphor oscilloscope is available, which combines the characteristics of an analog oscilloscope with a digital oscilloscope, in order to improve the accuracy of its measurements by increasing the number of samples. It also has a large number of functions that are worth exploiting, as it has the Windows 7 operating system, which means that you can develop several types of applications or graphical interfaces. We have programmed a graphical interface for impulse-type tests, specifically four tests: full wave ray pulse, cut wave pulse type, current pulse and maneuver pulse type, in order to be applied to equipment that can be coupled to A power system. To do this, national and international standards must be complied with, where a series of processes are defined; Within which 10 find electrical tests in the field of distribution and medium voltage. These tests show some technical and technological deficiencies. One of the most important deficiencies is that this operation is visualized on the oscilloscope, but the measurements of the normalized parameters, such as the time front, peak value and the time of Glue are taken manually. This is reflected in the quality of the information, it is also worth noting that performing this task can be very tedious and prolonged, in addition to generating noises and the oscilloscope does not deliver a pure signal, so some measures are often incorrect or A higher error rate, since we are actually visualizing noise and interference. That's why we improve the quality of impulse-type tests and the optimization of time for any test object in the laboratory. This application automates the taking of measures for this test and will support the development of student training in the area of ​​high voltage. The implementation of the above has been done through the GUIDE visual programming environment available in MATLAB, which facilitates The union between the mathematical part and the graphical user interface. We hope that this project is a great initiative to develop more studies related to this oscilloscope, since it is a great tool that the university has and is not being maximized.
