Fault Wave Recording Based on LabVIEW and Data Acquisition Board of Advantech

摘要

This paper presents a method of data acquisition system based on computer. With Labview6.0 of National Instruments (NI) and DAQ card of Advantech Company, we have finished data acquisition and fault wave recording of simulated EHV transmission line. It provides a recording and analyzing tool for the fault testing and the performance test for the relaying protection and automatic equipment. Practical tests in laboratory verify the validity of this scheme in improving the experiment level of laboratory as well as the teaching qualities for the university.
