Appendix A Reference Information
Calculating AC Line Impedance
If your system uses a line reactor, you must adjust AC line kVA (parameter 13:32 [AC Line kVA A]), and
AC line impedance (parameter 13:34 [AC Line Imped% A]) using the following equations and information:
For Converter Rated Volts, use the value of parameter 13:25 [Line Side Converter Rated Voltage].
For Converter Rated Amps, use the value of parameter 13:26 [Line Side Converter Rated Current].
Example
A drive system has:
A 2500 kVA transformer with 7% impedance
A linear reactor with 5% impedance
Converter Rated Volts of 480
Converter Rated Amps of 761
In this case:
Set parameter 13:32 [AC Line kVA A] to 2500.
Set parameter 13:34 [AC Line Imped% A] to 27, as found in the calculations below:
