In order to monitor, supervise and calibrate the active and reactive power as indicated in
figure
392 it is necessary to do the following:
1. Set correctly CT and VT data and phase angle reference channel PhaseAngleRef (see
Section “Setting of the phase reference channel”) using PCM600 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:
• general settings as shown in table 54.
• level supervision of active power as shown in table
55.
• calibration parameters as shown in table 56.
