Abstract

The vibration of windings and iron core causes the overall vibration of the transformer. Significant changes of transformer vibration condition will take place when the windings or core has fault, so the vibration method can be used to diagnose the transformer's potential fault. The characteristics and transmission route of the transformers' vibration are analyzed. The vibration of a certain transformer in converter station is picked up, using vibration measuring system. The test results are analyzed comparatively and maintenance suggestion is proposed.
