Application manual
The available measured values of an IED are depending on the
actual hardware (TRM) and the logic configuration made in
PCM600.
Measurement function application for a 400kV OHL

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
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.
