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
PhaseAngleRef
(see
settings for analog input modules in PCM600) 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
.
•
level supervision of active power as shown in table
.
•
calibration parameters as shown in table
.
