IMPORTANT REMARK! If power = -0.01 is shown for any of the phases
(codes 03, 09 and 15) and voltage and current are not zero for this phase, check out
following points:
- Assure that L1, L2 and L3 phases coincide in voltage and current.
- Correct polarity? Reverse the current transformer placed at this phase.
