Figure 202: Single line diagram for generator application
In order to measure the active and reactive power as indicated in figure 202, it is necessary to do
the following:
1. Set correctly all CT and VT data and phase angle reference channel
"") 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

value
On Function must be
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-
