Basic IED functions
SMAI1:13 – SMAI12:24: DFTReference = ExternalDFTRef to use DFTSPFC input of SMAI1:13 as
reference (SMAI7:7)
For task time group 3 this gives the following settings:
SMAI1:25 – SMAI12:36: DFTReference = ExternalDFTRef to use DFTSPFC input as reference
(SMAI7:7)
For task time group 4 this gives the following settings:
SMAI1:37 – SMAI12:48: DFTReference = ExternalDFTRef to use DFTSPFC input as reference
(SMAI7:7)

Figure 238: Configuration for using an instance in task time group 2 as DFT reference.
Assume instance SMAI4:16 in task time group 2 has been selected in the configuration to control the
frequency tracking for all instances. Observe that the selected reference instance (i.e. frequency tracking
master) must be a voltage type. Observe that positive sequence voltage is used for the frequency
tracking feature.
For task time group 1 this gives the following settings (see Figure
