General InformationHarmonic and Flicker measurement

Harmonic measurement

Main features

- Designed for measuring and analysis with - IEC 61000-4-7 :1991 & 2002- IEC 61000-4-15 :1997 & A1 (2003 New filter / Flickermeter 120V / 60 Hz)

- High resolution power analyzer for 1-or 3 phase application- Dual processor architecture for independent data acquisition- Windows based software with easy PASS / FAIL function- Simultaneously checks the AC power source output voltage- Real time multi-tasking data storage of voltage and current > 30 hours- Easy and simple handling with START / STOP button- Powerful documentation with direct export to Word- Data storage on computer for later analysis in the office- Class X library (create own limits for harmonic current)- Possibility to analyse a memorized data file with a different class at anytime- Self calibration function- Margin function (customized tolerance to selected limit)

Main characteristics for a full compliance requirement

- Dual processor architecture system based on a real time multi-tasking kernel to assure real time measurement

- Internal hard disk for long duration data storage- Wide input range (16 Bit A/D converter ) to avoid data lost by switching range

Accuracy of measurement

The signal conditioner uses a 16 bit A to D converter and a high perform-ance Motorola Digital Signal Processor to obtain highly accurate measure-ments.

An internal calibration routine allows the calibration of each channel. Thefigures below show the accuracy of the current input of a typical measuringsystem in comparison to the recommended accuracy of a class I equipmentaccording EN / IEC 61000-4-7.

Harmonic tests

In a simple screen the operator selects the desired standard for testing. Thesoftware presents all standard possibilities and guides the user through thesetup. The dual processor architecture and the multi-tasking real time kernelassure full compliance to EN / IEC / JIS C 61000-3-2 ,EN / IEC 61000-3-12 and EN / IEC 61000-4-7.

- Simultaneous display of voltage and current in time and frequency domain- Dynamic calculation of the limits in class C and D- Different color for harmonics above the standard limits- Cursor sensed display of harmonic voltage, current, frequency, limits, power, and phase

- Real time monitoring of the AC power source- High accuracy measurement displays Vrms, Irms, Vpeak, Ipeak- Numeric display of THD(u), THD(i), True power, Reactive power, Apparent power, Power factor, Crest factor(u), Crest factor(i)

- Display of remaining test time during the test- Stop button to finish the test- Selection of the class A...D at every time- Data storage on the internal DPA hard disk- FFT calculation based on measurements with rectangular windows with no gaps

Harmonic Analysis

At the end of the test, the data are uploaded from the DPA to the computerwhere the software automatically performs harmonic analysis according tothe selected standard.

The software provides summaryoverviews for each inspection criteriaas per EN/IEC/JIS C 61000-3-2
