PXI-based On-line Monitoring and Analyzing System for Power Transformers

CHEN Ting, CHEN Yitao, LI Zhaohui (Huazhong University of Science and Technology,Wuhan 430074, China)  
Aiming at the main potential fault characteristics of power transformers, a brand-new settlement called the on-line monitoring and analyzing system for power transformers is brought forward with the aid of PXI and LabVIEW virtual instrument platform. The system synthesizes the means of ultra high frequency detection of the partial discharge (PD) signal, ultrasonic locating of the PD sources, dissolved gas analysis, dielectric loss monitoring of the bushing and the electric current monitoring of the grounding iron core to analyze and judge the health of power transformers effectively. The hardware is dependable and the software is transplantable and expandable. This paper introduces the selection of the system hardware platform, the system framework and the software function modules in detail.
