Demagnetisation of grain-oriented electrical steels (GOES)
Stan Zurek
; Megger
Sažetak
The magnetisation processes in grainoriented electrical steels, which are the basic component of transformers cores, are very complex and depend on the amplitude and frequency of excitation. Nevertheless, demagnetisation frequency is of less significance because good quality procedure can result in the same demagnetised state. Demagnetisation is important for transformer testing, especially when using Sweep Frequency Response Analysis, as well as for saturation testing of current transformers.
