“…It can be observed in this case that the flux density magnitude did not exceed 1.2 Tesla for all sensors. Many other core loss models were proposed in the last decade [5][6][7][8][9][10][11] that considered the Steinmetz model as a base for the iron separation method. The recent time-domain dynamic core loss model proposed recently in [6] is used in this case study to compute the magnetic core losses.…”

“…The time-domain dynamic-core loss model proposed in [6] was initially applied to compute instantaneous core losses in small electromagnetic devices in both twodimensional and three-dimensional finite element analysis. The model proposed in [6] was extended [7][8][9][10] to compute the magnetic-core losses and their corresponding spatial distribution in large hydroelectric generators.…”

Predictions of the different magnetic core losses with acceptable accuracy are key parameters for temperaturerise calculations for considered up-rate in large hydro electrical machines. In this paper, available core loss model is used to compute the electromagnetic core losses in large hydro electrical machine during no-load and short-circuit modes. The obtained results are discussed and compared with the available test data.
