The two diagnostic methods consisting in the application of the low voltage impulses, respectively in the frequency response analysis are based on modifying of the local inductances and capacitances of the winding's structure, determined by the winding movement or by the other faults.
Cele doua metode de defectoscopie constind din aplicarea impulsurilor de joasa tensiune si respectiv analiza raspunsului in frecventa se bazeaza pe modificarea inductantelor si a capacitatilor locale ale structurii infasurarii, determinata de deformarea bobinelor sau de alte defectiuni.
The frequency response analysis (FRA) method consists in applying a sinusoidal signal of a variable frequency to one of the transformer's terminals, recording the response signals from the other terminals, the analysis and the interpretation of the results.
Metoda analizei raspunsului in frecventa (ARF) consta din aplicarea unui semnal de forma sinusoidala de frecventa variabila la una din bornele transformatorului, inregistrarea semnalelor de raspuns la celelalte borne, prelucrarea si interpretarea rezultate-lor.
