Web2.1 Steinmetz based models The ﬁrst group of models is based on the Steinmetz Equation (SE) [7] p Fe = C SEf α Bˆβ (1) where Bˆ is the peak value of the ﬂux density in the device under test. The three coefﬁcients C SE, α and β are determined by ﬁtting the loss model to curves from measurement data. Eq. (1) assumes a purely sinusoidal ﬂux density. WebCore losses occur in the steel core of the transformer due to the magnetizing current needed to energize the core. The magnetizing current remains the same during no-load and full load. Core losses are also known as iron losses in transformers. The core losses constitute two components: Hysteresis losses and eddy current losses.
