Page 16: Application Examples
The grid converter can charge the filter capacitors, magnetize the transformers, and synchronize the voltage measured from the grid side of the main circuit breaker. Thus the inrush currents and voltage transients occurring after the breaker closure are effectively avoided by using the Voltage Measurement Option OC7V0. | Danfoss A/S © 2024.01 AQ476649821259en-000101 / 136R0332... -
Page 17: Closed-Loop Ac Voltage Control
If there are transformers between the 2 circuit nodes, configure the phase difference of the converter voltage at the external grid measurement point.
