Product Description

 
Single Phase Power Quality Hamonic Analyzer Calibrator
Harmonic analysis
Function description
1. Perform the 2nd ~ 51st harmonic analysis on the measured signal, and test the total harmonic distortion rate,
odd and even times and each harmonic content.(note: test the 2nd ~ 21st harmonics according to the national
standard)
2. Test and analyze three-phase voltage and current, respectively, show the harmonic content of each harmonic in
the form of corresponding light bar chart, and display the percentage of corresponding harmonic content
accordingly.

voltage, current and sorting three options; select voltage and press "F2" key, choose current and press "F3", select
sorting and press "F5", show the each harmonic content of current or voltage according to the operation, and the
biggest harmonic on the scale line is full scale. If the harmonic is very small, only parts per ten thousand, such as
maximum 0.06%, the percentage value of the highest scale is 0.06%, and the subtle harmonic is amplified, clear at
a glance.

The instrument can test a total of 2nd ~ 51st harmonics, and show harmonic spectrum and give out the percentage
content of each harmonic. The 21st harmonic is used as an example in the following to calculate (the 51st harmonic
is calculated the same as the 21st harmonic)
Wherein:
Percentage content of each harmonic - refers to the percentage of the effective value of the 2nd ~ 21st harmonic
relative to the effective value of fundamental wave, defined as follows:
(of which i = 2, 3, 4 · · · · · · 21; Ui is the effective value of each harmonic, and U1 is the effective
value of fundamental wave.);
Harmonic order - refers to the multiples of fundamental wave frequency, relative to fundamental wave. If the
frequency of mains supply is 50Hz, the 2nd harmonic is 100Hz AC component, the 3rd harmonic is 150Hz AC
component and so on.

The scale line - the biggest harmonic is full.
Harmonic pollution to power grid is becoming more and more serious, so the harm caused by harmonics can not
be ignored, mainly reflected in:
1. Greatly increasing the chance of resonance in power grid, thus causing the risk of accidents arisen from very
high overcurrent or overvoltage;
2. Increasing additional loss, and reducing the efficiency of power generation, transmission and power equipment
and the equipment utilization;
3. Increasing the losses to electrical equipment (rotary motors, capacitors, transformers, etc.), accelerating the
insulation aging, and thus shortening the service life;
4. Enabling the relay protection and automatic device, computer systems, and a lot of electrical equipment to run
abnormally;
5. Leading to the metering and measuring instruments (such as: energy meter) not to give correct instructions or
measurement;
6. Interfering with the communication system, lowering down the quality of signal transmission, disturbing the
normal transmission signal, and even damaging the communications equipment.
