Figure 2-45 Distance protection topology for 2 ends with 2 devices - example
For a protected object with more than two ends (and corresponding devices), the third
end is allocated to its device ID at parameter addresses ,'2)5(/$<. A
maximum of 3 line ends is possible with 3 devices. Figure 2-46 gives an example with
3 relays. During the configuration of the protection functions the number of devices re-
quired for the relevant case of application was set in address 180%(52)5(/$<.
Device IDs can be entered for as many devices as were configured under that ad-
dress, no further IDs are offered during setting.
