Abstract:

In order to apply the insulation condition evaluation of transformers in dielectric frequency response method to the actual operation，the theory of dielectric frequency response is introduced firstly． Then the dielectric frequency response system is studied which consists of the micro current measurement system，signal acquisition，signal processing and software etc．At last，the system is applied to the field testing and evaluation for the condition of 220 kV transformers．
