Figure 391: Single line diagram for transformer application
In order to measure the active and reactive power as indicated in figure 391, it is
necessary to do the following:
1. Set correctly all CT and VT and phase angle reference channel PhaseAngleRef
(see Section “Setting of the phase reference channel”) data using PCM600 for
analog input channels
2. Connect, in PCM600, measurement function to LV side CT & VT inputs
3. Set the setting parameters for relevant Measurement function as shown in the
following table
