Type ARS 16 Harmonics & Flicker Analyzer

Type ARS 16
Harmonic Analysis / Flicker Analysis

Type ARS 16

The Analyser Reference System type ARS contains the core of the well known and reliable analyzer (Ducati/Boconsult B10) for the measurement part, the standard impedance according to IEC/EN 60725 as well as a phase- and current range switching.

It allows harmonics measurements according to IEC/EN 61000-3-2 and flicker measurement
according to IEC/EN 61000-3-3.

All the required diagram connections for the two types of measurement are performed automatically by ARS without any manual operation: this increases the reliability of the measurement avoiding any possible wiring error of the operator and ensures fast and reasonable operation with the test system.

Special Features:
Double FFT for simultaneous check of the source during the EUT measurement in harmonic analysis

Simultaneous two-channel measurement for source check (flicker measurement)

Harmonics & Flicker Generator
HFG02 EN61000-3-2 : 2014 EN61000-3-3 : 2014		The Harmonics & Flicker Generator (HFG02) is a multifunction electronic load for the purpose of verifying harmonic and flicker test equipment. It provides an easy and reliable way to externally check the performance of the measurement system to the EN/IEC 61000-3-2 harmonics and interharmonics and EN/IEC 61000-3-3 flicker standards. A reference source is particularly useful where there is little intuitive sense of the expected response and the tests rely on software control and calculation to produce a result.

HFG01 EN61000-3-2 : 2014 EN61000-3-3 : 2014		The Harmonics & Flicker Generator (HFG01) has been designed by York EMC Services Ltd for the purpose of verifying harmonic and flicker test equipment. Until now there has been no easy and reliable way to externally check the performance of the measurement system to the EN/IEC 61000-3-2 harmonics and EN/IEC 61000-3-3 flicker standards. The HFG01 allows the user to periodically verify their test equipment, ensuring compliance with standards and laboratory quality procedures. The unit provides a series of harmonic and flicker disturbances of a nominal but stable level. The generator may therefore be used to verify the stability of a measurement system. Alternatively due to its stability it may be used as a transfer standard from a calibrated system. Stable load simulation Repeatable measurements Injects harmonics to EN61000-3-2 and flicker to EN61000-3-3 Evaluation of test systems specifically to EN standards Compact and Portable Comparisons between multi-site test environments
Applications Harmonics and flicker measurement systems validation and verification Reference source for: Daily pre-test check Long-term performance monitoring Comparison of different harmonics and flicker measurement systems	Operation The unit is a standalone device and requires no additional equipment. A four-way rotary switch selects the mode of operation. The modes are defined by firmware running on a micro-controller. This will enable the characteristics of the generator to be reprogrammed in line with future changes to the standards. The HFG01 simulates equipment under test (EUT), generating known, repeatable levels of harmonic and flicker disturbance in one of four modes of operation. In Steady State harmonics (SS) mode, a harmonic-rich current waveform is generated, allowing the harmonic measurement system to be verified. In this mode the generator simulates Class D equipment and produces harmonic levels that will fail the EN/IEC61000-3-2 pre A14 and A14 Class D limits. This mode will pass EN/IEC61000-3-2 pre A14 and A14 Class A limits. Fluctuating harmonics (FL) mode alternates between two distinct current waveforms over a 10-second cycle. This mode again fails the EN/IEC61000-3-2 pre A14 Class D limits but passes the A14 limits. In flicker test mode, a fixed level of mains disturbance is generated at a rate of 8.33Hz or 1Hz. When tested to EN/IEC61000-3-3, the 8.33Hz rate produces a P_st >1, which lies above the limit line. The 1Hz setting produces a P_st <1, which falls below the same limit.

Overload protection

The AC1000A is an innovative, low cost, pure power source designed specifically for use with a harmonics analyzer such as the Laplace AC2000A, permitting compliance quality measurements to EN61000-3-2.

The AC supply available at a standard wall socket is usually distorted. This comes about because of nonlinear loads (non-resistive loads) on the AC supply such as transformers, fluorescent lights, switched-mode power supplies etc. In a typical load there are rectifiers and capacitors that cause current to be drawn from the supply only near the peak of the waveform. The effect of this is to flatten off the top of the sine wave causing significant distortion.

In a typical factory environment this distortion can be so significant that the distortion is easily visible using an oscilloscope.

EMC legislation (EN61000-3-2) has made mandatory the measurement of harmonic current produced by electronic equipment, and requires that the source supply provides a pure voltage waveform to the equipment under test. The harmonic currents can vary significantly when a pure source is used so it is important that any testing is performed with a device such as the AC1000.

Compact and portable the AC1000 is rated up to 1000 V.A for 230 V operation and will supply 1000 V.A at 230 V input at up to 35°C ambient. In contrast to other techniques which use a passive filtering approach, the AC1000 uses an innovative technique which actively corrects the AC supply to produce a harmonically pure output.

The ACl000 is also very useful for stress testing power supplies in electronic equipment. The use of a harmonically pure, distortion free device - such as the ACl000A - is essential to fully stress and evaluate the power supply under test.
