Abstract: Introduction was made to a fault case of 11 0 kV capacitive voltage transformer (CVT) founded in condition-based maintenance system. The system integrated the application of infrared thermometry and oil chromatographic technique to carry out state diagnosis. It was initially judged that there existed serious overheating phenomena inside the B-phase voltage transformer. The electrical test and the strip inspection etc. methods were used to verify the results of fault diagnosis, which embodies that the condition-based maintenance system could effectively grasp the running state of voltage transformer and diagnosis faults timely and accurately.
Key words: infrared thermometry technique; oil chromatographic technique; capacitive voltage transformer (CVT); electrical test; equipment disintegration
