Figure. 5.2.1 - 63. Common phase polarity problems.
The following image presents the most common problems with network rotation (mix phases). These
problems can be difficult to find because the measurement result is always the same in the relay. If two
phases are mixed together, the network rotation always follows the pattern IL1-IL3-IL2 and the
measured negative sequence current is therefore always 1.00 (in. p.u.).
