4.1.7.3 PROTECTION ELEMENTS

This option shows all the protection-grouped elements available in the relay as shown in Table 1–9:. Each of these groups
includes the specific protection units of the same type. For example phase currents group includes TOC, IOC, directional
units, etc. There are three groups available, so there are three protection units of each function that can work in grouped
mode or ungrouped (altogether).
