Abstract :
In this case 270,5 MVA turbogenerator was tested. The goal of the test was to diagnose the quality of the generator by using the on-line leakage field analysis during the normal machine operation. The leakage field was measured using the specially designed search coil. The search coil voltage was analyzed in time domain and in frequency domain using FFT.
