15.1.4.1 Setting examples
SEMOD54481-4 v5
Three setting examples, in connection to Measurement function (CVMMXN), are
provided:
• Measurement function (CVMMXN) application for a OHL
• Measurement function (CVMMXN) application on the secondary side of a
transformer
• Measurement function (CVMMXN) application for a generator
For each of them detail explanation and final list of selected setting parameters
values will be provided.
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
SEMOD54481-12 v11
Single line diagram for this application is given in figure 135:

In order to monitor, supervise and calibrate the active and reactive power as
indicated in figure 135 it is necessary to do the following:
1. Set correctly CT and VT data and phase angle reference channel
PhaseAngleRef (see Section “Setting of the phase reference channel”) 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:
