Research and Implementation of High Precision Power Parameter Acquisition Technology Based on LabVIEW

Abstract

On the analysis of function requirements of the power parameter acquisition system during the test for intelligent low-voltage electrical apparatus, a high precision power parameter acquisition system based on LabVIEW was proposed. The hardware platform of the acquisition system was made up of industrial control computer, high precision sensors and high speed data acquisition card. According to the measuring principles and calculation methods of different power parameters, corresponding data acquisition, analysis and processing software is developed by LabVIEW software. Finally, the application example shows that the acquisition can carry out real-time and accurate acquisition and processing on related power parameters.
