It can be stated that the phase shift between switched current and recovery voltage
does not depend on the power factor, but is determined by the relationship of the
values of the transition resistors and the impedance of one tap section. Considering
the fact that a reactance of 50 mO of one tap section of the tap winding is on high
side and the resistance values of the transition resistors used in the calculation are
usual, one can state that the phase shift between switched current and recovery
voltage is in the range of I degree. A phase shift of 1 degree corresponds to only
of the peak value of the recovery voltage sine wave and therefore can be ,, .C
neglected
