3-Winding Transformer Impedance in IEC Short Circuit Study While calculating transformer impedance in IEC short circuit study impedance correction factor (KT) is used as per IEC 60909.

Where, KT - Impedance Correction Factor Cmax - Voltage factor related to the terminal voltage of the network connected to the low-voltage Side of the network transformer xT - Relative Reactance of the transformer ZTK = ZT X KT So for a 3-Winding Transformer Transformer
