Chapter 5 Power Quality Monitoring
Harmonic Magnitude and Angle
The power monitor calculates the RMS magnitude and angle of each individual
harmonic. Results are calculated for harmonics DC to 63 (DC to 127th for the
M8 model) for all voltage and current channels. Each magnitude is expressed in
rms volts or rms amps. DC offset is always zero for current channels. Only
directly connected voltage channels return non-zero DC offset values.
Angles are expressed in degrees, with zero degrees corresponding to the time
stamp of the metering results.
