DIFFERENTIAL AND RESTRAINT
The metered differential current, restraint current, second harmonic current, and fifth harmonic current are displayed for
each phase. Refer to the
Percent differential
section in chapter 5 for details on how these values are calculated.
If differential current in any phase is below the hard-coded cutoff of 0.04 pu, then the differential, 2nd harmonic, and 5th
harmonic currents are forced to zero.
