Setting examples
Three setting examples, in connection to Measurement function (CVMMXN), are
provided:
• Measurement function (CVMMXN) application for a 400 kV 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.
