RAMOS GUARDARRAMA, Josnier; CANASI PINEIRO, Mercedes y MARTINEZ BARBADO, José Angel. Implementation of embedded system DIL/NETPG with Labview for test to transformers. Energética [online]. 2012, vol.33, n.1, pp. 78-86. ISSN 1815-5901.
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.
