In order to monitor, supervise and calibrate the active and reactive power as indicated in figure
it is necessary to do the following:
1. Set correctly CT and VT data and phase angle reference channel
"Setting of the phase reference
2. Connect, in PCM600, measurement function to three-phase CT and VT inputs
3. Set under General settings parameters for the Measurement function:

higher measurement accuracy. Typically no scaling

higher measurement accuracy. Typically no angle

0.00 Typically no additional filtering is required
25 Set minimum voltage level to 25%. Voltage below
25% will force S, P and Q to zero.
3 Set minimum current level to 3%. Current below
3% will force S, P and Q to zero.
