Figure 428: 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
for numbering):
SMAI1:1 – SMAI12:12:
DFTReference = ExternalDFTRef to use DFTSPFC input as reference
(SMAI4:16)
For task time group 2 this gives the following settings:
SMAI1:13:
DFTRefExtOut = DFTRefGrp4 to route SMAI4:16 reference to the SPFCOUT output,
DFTReference = DFTRefGrp4 for SMAI1:13 to use SMAI4:16 as reference (see Figure
)
SMAI2:14 – SMAI12:24:
DFTReference = DFTRefGrp4 to use SMAI4:16 as reference.
For task time group 3 this gives the following settings:
SMAI1:25 – SMAI12:36:
DFTReference = ExternalDFTRef to use DFTSPFC input as reference
(SMAI4:16)

The protection and control IEDs may have a complex configuration with many included
functions. To make the testing procedure easier, the IEDs include the feature that allows
individual blocking of a single-, several-, or all functions.
This means that it is possible to see when a function is activated or trips. It also enables the
user to follow the operation of several related functions to check correct functionality and to
check parts of the configuration, and so on.
