Figure 158:
In order to monitor, supervise and calibrate the active and reactive power as indicated in figure
is necessary to do the following:
1.
Set correctly CT and VT data and phase angle reference channel PhaseAngleRef using
PCM600 for analog input channels
2.
Connect, in PCM600, measurement function to two-phase CT and VT inputs
3.
Set under General settings parameters for the Measurement function:
