Figure 45: 3PHSUM setting parameters example-showing that 3PHSUM is using
the External DFT reference coming indirectly from SMAI3
Figure 46 shows an example of wrong connection of 3PHSUM and PHASORREPORT
blocks in ACT where SMAI3 is configured as the reference block for DFT reference
external out (DFTRefExtOut) and 3PHSUM uses external DFT reference (from
SMAI3).

blocks in ACT
If settings for PMUREPORT instances (PHASORREPORT1 instances 1 and 2 above)
differ for SvcClass or ReportRate, then the synchrophasor reported by PHASOR2
connection from PHASORREPORT1 instance 2 will not be compliant with IEEE
C37.118 standard. The reason is as in the rule 2, the filtering in SMAI/3PHSUM block
