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.
It is also serving
as a DC power source
to cover the
requirements as per
IEC/EN 61000-4-29
for voltage dips and
interruptions on DC
supplies.
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.

HFG01

: 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 Pst >1, which lies above the limit
line.
- The 1Hz setting produces a Pst <1,
which falls below the same limit.

The ACl000A 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.
