Implementación de un sistema DIL/METPC con Labview para ensayos a transformadores

this paper presents the design and validation for operation of an automatic measurement system for the laboratory of distribution transformers of the cipel. the system makes the test for no-load looses and excitement current, load losses and impedance voltage; and temperature rise according to the ieee std c57.12.90tm-2006 standard. a data acquisition system based on the dil/netpc dnp/1110 manages the sampling and control tasks; lead by three programs written in labview. the results are processed and shown for each one of the tests. a core controller of gnu/linux joint to an application in user area allows to obtain a sampling frequency of 20.22 khz, according to the performance of the system hardware. the transfer of information between the embedded system and the lead programs is accomplished through a connection with socket tcp/ip.
