The DPA500N harmonics and flicker analyzer is used for single phase applications.

Harmonics and inter-harmonics are caused by modern electronic power conditioning modules. Such, mostly non-linear, modules to control loads and to reduce power consumption is the source of voltage at unwanted frequencies superposed on the supply voltage.
Voltage fluctuations caused by varying load currents may influence the luminance or the spectral distribution of lighting systems. The impression of the unsteadiness of visual sensation induced by this light stimulus is called flicker.

The DPA 500N is a fully compliant analyzer for harmonics and flicker as per the latest IEC/EN 61000-3-2, IEC/EN 61000-3-3 and JIS C 61000-3-2 requirements. It follows the design specifications as per IEC/EN 61000-4-7:2002 and Am.1:2008 (for Class A instruments) and IEC/EN 61000-4-15:2003.
Based on a real-time kernel and equipped with its own hard disk it allows to record the measuring data continuously without any gaps or overlapping. The rectangular measurement window is synchronized to each group of 10 or 12 cycles of the mains supply frequency (50Hz or 60Hz) by means of a digital PLL (Phase Lock Loop). A wide-range current input (up to 50A) avoids loss of measured data due to range switching that would occur when using different shunt resistors.
The classification of the measurement can be selected at any time, before or after the measurement has been performed. During all measurements the AC supply voltage is measured simultaneously with the current.
The built-in flicker impedance, which is automatically selected when doing flicker measurement, makes the
DPA 500N a complete single-box unit for both harmonics and flicker analysis.
By means of an external current clamp (optional) the current range can be extended up to 140Arms and more.

NetWave 7 - Simulation of the most required power supply phenomenon

The NetWave 7 is a single phase AC power source, specifically designed to meet the requirements as per IEC/EN 61000-4-13, IEC/EN 61000-4-14, IEC/EN 61000-4-17, IEC/EN 61000-4-28.

Its output power with low distortion and high stability, even if supplying dynamic loads, guarantees full compliant measurements for harmonics and flicker testing as per IEC/EN 61000-3-2, JIS C 61000-3-2 and IEC/EN 61000-3-3 as well as per IEC/EN 61000-3-11 and IEC/EN 61000-3-12.
Additionally, the NetWave 7 is also well suited for avionics testing as per DO-160, Airbus ABD0100 and Boeing as well as per MIL-STD-704.

NetWave 7 - The powerful multitalent for AC and DC supply simulation

The programmable AC and DC power source with its wide frequency bandwidth offers powerful waveform generation capabilities for various test applications in the EMC area and for avionics testing.
Based on a Dual-Processor technology, with an integrated high-performance PC, a digital signal processor (DSP) and equipped with a hard disk the NetWave is capable to generate and record waveforms in realtime.
According to standard requirements a pure sinusoidal voltage is needed for harmonics and flicker measurements. The output voltage of the NetWave 7 is therefore guaranteed to have a very low distortion (THD) of less than 0.1% regardless of the load.
No matter whether waveforms are programmed of segments or of single points (normally resulting in MBs of data) the NetWave 7 will do. Recording of waveforms with up to 1GByte is easily possible. The measuring channels are designed to handle upt to +/- 500Vpeak and +/-150Apeak with 16bit resolution.
Interfaces like GPIB, Ethernet and USB (to connect a memory stick) are common features with the NetWave 7.

Harmonics and Flicker Generator 01

HFG01

EN61000-3-2 : 2004

EN61000-3-3 : 2004

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.
