Z% impedance greatly affects the amount of voltage drop on the transformer. At the time of short circuit testing the magnitude of impedance changes should not change more than 3%, and if more declared failed production.
The magnitude of the impedance must be equalized when the transformer system is installed parallel to avoid unbalance currents.
