4. Experimental identification of the capacitive part

4.1 Equivalent circuits with and without couplers

In the , we have introduced and justified the two circuits (shown in figure 25 ) to model the capacitive behavior of a two-winding transformer. Note that they are connected between the same four points and, in line with our previous assertions, they are in parallel on the circuit representing magnetic coupling. To see for yourself, simply evaluate the voltage supported by each capacitor: it's a linear combination (with frequency-independent coefficients) of the three external voltages (V ₁ to V ₃ ...
