In order to monitor, supervise and calibrate the active and reactive power as indicated
in figure 306 it is necessary to do the following:
1. Set correctly CT and VT data and phase angle reference channel PhaseAngleRef
(see section "Analog
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 210.
• level supervision of active power as shown in table 211.
• calibration parameters as shown in table 212.
