The available measured values of an IED are depending on the
actual hardware (TRM) and the logic configuration made in
PCM600.

In order to monitor, supervise and calibrate the active and reactive power as
indicated in figure
97 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 33 .
• level supervision of active power as shown in table 34 .
• calibration parameters as shown in table 35 .
