Rescarch And Application Of Diagnosis Technology On Integrated Fault Test Of Power Transformer

The transformer is one of important monitoring equipments in power system. The running state of the device directly influences the security of the system. So testing and diagnosing the state of the transformer has great significance. The comprehensive diagnostic technique is produced by integrating conventional testing techniques and single diagnostic techniques. The paper proposes a technique combined by comprehensive test and comprehensive diagnosis. Based on comprehensive testing technique establishing the fault diagnosis model can effectively avoid the disorder of the diagnostic work and improve the capability of fault searching. Comprehensive test diagnostic technique uses a variety of testing and diagnosis methods to analyze the transformer’s fault condition. Use the test results to support the implementation of the fault diagnosis method. Use the contacts among the single fault diagnosis method to complete the comprehensive diagnosis. The method has achieved good diagnostic results through practical application.
