Power frequency magnetic field interference suppression method for online frequency response analysis of power transformers

The Journal of Engineering
Frequency response analysis is widely used for the offline diagnosis of winding deformations in power transformers. To apply this approach to a working transformer, the magnitude of the response current needs to be measured by using Rogowski coil sensors
