In order to monitor, supervise and calibrate the active and reactive power as indicated in figure
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 three-phase CT and VT inputs
3. Set under General settings parameters for the Measurement function:

value
On Function must be On
1.000 It can be used during commissioning to achieve higher
measurement accuracy. Typically no scaling is required
0.0 It can be used during commissioning to achieve higher
measurement accuracy. Typically no angle
compensation is required. As well here required
direction of P & Q measurement is towards protected
object (as per IED internal default direction)
