Figure 43 shows an overview of the PMU functionality and operation. In this figure,
only one instance of PMUREPORT (PMUREPORT1) is shown. Note that connection
of different signals to the PMUREPORT, in this figure, is only an example and the
actual connections and reported signals on the IEEEC37.118/1344 can be defined by
the user.

Figure 43: Overview of reporting functionality (PMUREPORT)
The TRM modules are individually AC-calibrated in the factory. The calibration data
is stored in the prepared area of the TRM EEProm. The pre-processor block is
extended with calibration compensation and a new angle reference method based on
timestamps. The AI3P output of the preprocessor block is used to provide the required
information for each respective PMUREPORT phasor channel. More information
about preprocessor block is available in the section

6.2.3.1 Frequency reporting
By using patented algorithm the IED can track the power system frequency in quite
wide range from 9 Hz to 95 Hz. In order to do that, the three-phase voltage signal shall
be connected to the IED. Then IED can adapt its filtering algorithm in order to
properly measure phasors of all current and voltage signals connected to the IED. This
