In order to monitor, supervise and calibrate the active and reactive power as indicated in
figure 241
1. Set correctly CT and VT data and phase angle reference channel
Section
2. Connect, in PCM600, measurement function to three-phase CT and VT inputs
3. Set under General settings parameters for the Measurement function:
