The magnetizing branch susceptance deviation in percent of nominal value. The actual susceptance is calculated as follows:<br/>calculated magnetizing susceptance = b(nominal) * (1 + b(from this class)/100). The b(nominal) is defined as the static magnetizing susceptance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form.<br/><br/>

The magnetizing branch conductance deviation in percent of nominal value. The actual conductance is calculated as follows:<br/>calculated magnetizing conductance = g(nominal) * (1 + g(from this class)/100).

The voltage at the tap step divided by rated voltage of the transformer end having the tap changer. Hence this is a value close to one.<br/>For example, if the ratio at step 1 is 1.01, and the rated voltage of the transformer end is 110kV, then the voltage obtained by setting the tap changer to step 1 to is 111.1kV.<br/><br/>

The series reactance deviation in percent of nominal value. The actual reactance is calculated as follows:<br/>calculated reactance = x(nominal) * (1 + x(from this class)/100). The x(nominal) is defined as the static series reactance on the associated power transformer end or ends. This model assumes the star impedance (pi model) form.<br/><br/>
