Chapter7 Harmonic Measurement Function

7.1 Overview

Introduction to soft keys of interface
This chapter describes the characteristics and operations of the voltage
harmonic measurement function of IT8600 electronic load.
The bandwidth of IT8600 electronic load is 100kHZ. The voltage harmonic
measurement of high speed and wide dynamic scope can be realized. In the
harmonic mode, the active power, reactive power, phase and voltage harmonic
distortion factor (UTHD) of voltage harmonics can be tested. In addition, IT8600
can be used for measuring multiple harmonics. At most 50 harmonics of
fundamental frequency can be measured.
IT8600 electronic load can display harmonic parameters in the list or bar chart
form to make the analysis of test result clear.
Select [Harmonic] and the following initial interface of harmonic measurement
will appear.
Description of the harmonic measurement interface:
Parameter Name Parameter Description
Thd Formula Distortion factor calculation formula.
% r: displaying harmonics in the form of percentage to
the overall voltage amplitude of all harmonics.
% f: displaying harmonics in the form of percentage to
the fundamental voltage.
CHART Bar chart form.
LIST List form.
