Infeed: Line currents not symmetrical

What does 206207 mean?

The asymmetry of line currents in the infeed is too high, most likely due to a failure in one of the line phases. This imbalance can lead to improper operation of the infeed unit and potentially damage components if not resolved. It indicates an issue with the quality or integrity of the incoming power supply.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the previous alarm A06205 and its alarm value for more specific diagnostic information related to line conditions.

2. 4

   Measure the line voltages and currents to confirm symmetry across all phases.
