B. Practical Determination of the Transformer Parameters
The first step is the determination of inductances Lm and
Ld. This task requires two considerations. The first one is that
the leakage inductance can be negligible if compared with
the magnetizing inductance. The other consideration is that
the use of a low frequency in the measurements allows
consider the effects of the winding capacitances insignificant.
Therefore, to low frequencies, the equivalent circuit to the
high frequency high voltage transformer presented in Fig. 4
can be used
