Calculations

Supporting calculations

The rated apparent power of the Line Module is:

The specific conductance value of the medium-voltage cable is:

= 2 ∙ ∙ '

In turn, the reactance of the medium-voltage cable is calculated as follows:

= '

∙

The active resistance of the medium-voltage cable is calculated as follows:

∙

The specific conductance value of the low-voltage cable is:

= 2 ∙ ∙ '

In turn, the reactance of the low-voltage cable is calculated as follows:

= '

∙

The active resistance of the low-voltage cable is calculated as follows:

∙

The specific conductance value of the converter connecting cable is calculated to be:

= 2 ∙ ∙ '

In turn, the reactance of the converter connecting cable is calculated as follows:

= '

∙

The active resistance of the converter connecting cable is calculated as follows:
