For the purpose of analysis exact equivalent circuit of a transformer is usually replaced by an approximate equivalent circuit.
In doing so errors introduced due to winding copper loss and core loss are of different nature.
Due to this, the analysis by approximate equivalent circuit gives fairly satisfactory results.
Under the circumstances, which one of the following statements is correct in respect of losses referred to approx. equivalent circuit as compared to exact equivalent circuit?
A. This accounts for somewhat lesser primary winding copper loss and less core loss.
B. This accounts for somewhat lesser primary winding copper loss and more core loss.
C. This accounts for somewhat greater secondary winding copper loss and less core loss.
D. This accounts for somewhat lesser secondary winding copper loss and core loss.
