The snapshot of each phase current DFT magnitude and angle values (FLTILxMAG/FLTILxANG), each
phase voltage DFT magnitude and angle values (FLTULxMAG/FLTULxANG), neutral current DFT
magnitude and angle (FLTINMAG/FLTINANG), and neutral voltage DFT magnitude and angle
(FLTUNMAG/FLTUNANG) are stored at the positive edge of the binary input TRIP.
The SMPPTRC function monitors and reports the following data at the output, considering the default
setting parameters mentioned in
