RIP LOGIC
(94)
The simple trip logic function operates according to the functionality required by the IEC
61850 standard for the “Trip logic logical node”.
This simplified software module can be
applied if only three-phase trip commands are required, that is, phase selectivity is not
applied. The function receives the trip requirements of the protective functions implemented
in the device and combines the binary signals and parameters to the outputs of the device.
