Operation principle

Summation block 3 phase 3PHSUM receives two groups of three-phase signals from Signal matrix
for analog inputs (SMAI) functions. The outputs are a linear combination of the corresponding input
signals, as per the SummationType setting.
The input signal REVROT is used to reverse the phase order of the output signal. DFTReference and
FreqMeasMinVal should be set the same as in the source SMAI functions.
Activating the BLOCK input will force all outputs of the function to 0.

Functionality

The purpose of the 3PHSELECT function is to connect the receiver functions to one out of two three-
phase analog signals. For example, in case of a tie-breaker application, where the connected load
can be supplied by either of the two sources available (refer
controlled by the IED in such a way that it can switch between the two sources (Source 1/Feeder 1
and Source 2/Feeder 2) seen by the breaker as required by the user. The 3PHSELECT function
allows selecting any of the available analog signals as reference signal or feedback signal without
the need for external logic.
