Figure 100: Single line diagram for 380kV OHL application
In order to monitor, supervise and calibrate the active and reactive power as indicated in figure
100 it is necessary to do the following:
1. Set correctly CT and VT data and phase angle reference channel
for analog input channels
2. Connect, in PCM600, measurement function to three-phase CT and VT inputs
3. Set under General settings parameters for the Measurement function:
