Setting examples

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
Single line diagram for this application is given in figure 309:

In order to monitor, supervise and calibrate the active and reactive power as indicated
in figure 309 it is 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:
