488 Appendix: ESP with step-up transformer and sine filter
Current calculation
For ESP with sine filter and step-up transformer instead of using the motor rating
plate data, set parameter
supply voltage of the drive (example: 690 V). Also set the parameter
to
Where U
1
and U
2
are the primary and secondary voltages of the step-up transformer
respectively.
Primary and secondary voltage calculation
Required data:
Motor:
Cable:
If the cable characteristics are not known, typical values can be used:
Motor data:
Nominal impedance,
Resistive component,
Reactive component,
Cable reactance at frequency
