Depending on the type of device ordered and the device connections, some of the operational measured values
listed below may not be available. The phase–to–ground voltages are either measured directly, if the voltage
inputs are connected phase–to–ground, or they are calculated from the phase–to–phase voltages V
and the displacement voltage V
