CURRENT HARMONICS
Harmonics: 2nd to 25th harmonic: per phase, dis-
played as a % of f
quency phasor)
THD: per phase, displayed as a % of f
Accuracy:
HARMONICS: 1. f > 0.4pu: (0.20% + 0.035% / harmonic) of
1
reading or 0.15% of 100%, whichever is
greater
2. f < 0.4pu: as above plus %error of f
1
THD: 1. f > 0.4pu: (0.25% + 0.035% / harmonic) of
1
reading or 0.20% of 100%, whichever is
greater
2. f < 0.4pu: as above plus %error of f
