The method of measuring the tank vibration for on line monitoring the power transformer is described. How to extract the core’s and the winding’s vibration signals is also discussed and analyzed.According to the measured frequency domain characteristics of the tank vibration signals
we have described the feature of the core’s and the winding’s vibration signals.In conclusion
measuring the tank vibration to monitor the power transformer is more feasible than measuring the noise.
