Transformer Condition Monitoring System Based on Virtual Instrument Technology

In the light of the drawback that exists in the regularly overhaul of currently generally adopted power transformer, the online monitoring system of power transformer is developed based on the virtual instrument technology, the prevision in advance of transformer condition is realized. The paper introduces the key technology about using Labview under Windows operating system to realize the functions of data acquisition, store real-time data at high speed, database administration, multi-oscillograph interface and cursor etc. The system has good characteristics of real-time, friendly interface and convenient in operation. Practice shows that using the virtual instrument technology the transformer condition monitoring system can be developed in high efficiency, the system developed has a strong function and can be maintained and expanded conveniently.
