Abstract :
This paper shows a way to realize onsite-diagnostics of power transformers in service by using the transfer function method. One main aspect is represented by the sensitivity of the method concerning mechanical displacements and interturn faults. Three types of comparison of transfer function results are shown and it is described, how results can be evaluated without fingerprints from former measurements
