Figure 2.2.2-3. Third and last menu (next on the right) of I>> 50/51 stage
This is the menu for registered values by the I>> stage. Fault
logs are explained in chapter 2.2.4.
This is the latest of the eight available logs. You may move
between the logs by pressing push buttons ENTER and
then RIGHT or LEFT.
The overcurrent fault has been detected in phases L1 and
L2 (A & B, red & yellow, R&S, u&v).
The fault current has been 2.86 per unit.
The average load current before the fault has been 0.99 pu.
The elapsed operation delay has been 81% of the setting
0.60 s = 0.49 s. Any registered elapsed delay less than 100
% means that the stage has not tripped, because the fault
duration has been shorter than the delay setting.
The setting group has been 1. This line can be reached by
pressing ENTER and several times the DOWN button.
