Figure 12.7 Measured and calculated voltages transferred to the secondary of the
30 kVA transformer under different load conditions: (a) voltage applied
to the HV terminals (standard 1.2/50 ms waveform, with amplitude of
1.70 kV for panel b and 0.95 kV for panel c; (b) transferred voltages
(no-load condition) corresponding to panel a; (c) transferred voltages
(balanced load of 50V) corresponding to panel a with amplitude of
0.95 kV; (d) voltage applied to the HV terminals (panels e and f ); (e)
transferred voltages (no-load condition) corresponding to panel d; ( f)
transferred voltages (balanced load of 50V) corresponding to panel d
