Current Phase Sequence

The LTMT main unit detects the current phase sequence of three-phase motor supply.

  • L123: L1 current at angle 0°, L2 current at angle 240°, L3 current at angle 120°.

  • L132: L1 current at angle 0°, L2 current at angle 120°, L3 current at angle 240°.

  • CTWF: Current transformer wiring fault detected by the LTMT main unit. For example, one of the three phases is wired in opposite direction.

NOTE: Current imbalance is not available in single-phase mode.
