Figure 100:
In order to measure the active and reactive power as indicated in figure 100, it is necessary to do the
following:
1. Set correctly all CT and VT data and phase angle reference channel PhaseAngleRef using PCM600
for analog input channels
2. Connect, in PCM600, measurement function to the generator CT & VT inputs
3. Set the setting parameters for relevant Measurement function as shown in the following table:

value
On Function must be On
1.000 Typically no scaling is required
0.0 Typically no angle compensation is required. As well
here required direction of P & Q measurement is
towards protected object (as per IED internal default
direction)
Arone Generator VTs are connected between phases (V-
connected)
0.00 Typically no additional filtering is required
