Control Characteristic with Z Compensation
X and R Compensation (LDC-XandR)
During the application of the X and R compensation, you need the phase data. With this data, it is possible to
precisely compensate the voltage drop of the transmission lines. The following figure shows the effect of this
compensation type.
