Infeed: Line currents not symmetrical

What does 206207 mean?

This fault indicates excessively high asymmetry in the line phase currents, with the most probable cause being the failure of one or more line phases. This condition leads to imbalanced loading of the infeed unit. If left unaddressed, this can result in overheating of components, reduced efficiency, and potentially premature failure of the infeed unit or connected equipment due to prolonged electrical stress.
