(3) Harmonic measurement(PF9810/PF9811)
Table 2.3
Function of harmonic measurement
Method
Phase-locked loop synchronization method(PLL)
Analysis of
Projects
The effective value of each harmonic component and relative value of
voltage, current and active power
The relative values of total harmonic distortion of the voltage and current
The calculation method of harmonic distortion is IEC
the total calculation method of harmonic distortion can be set IEC or CSA in
computer.
Frequency range
The fundamental frequency of PLL source is between45Hz and 65Hz.
PLL Source
The input signal o should be more than 50% of the range.
