1 Description
The product family standard for household equipment IEC 555-2 is applicable for a power line current
< 16 A per phase published 1982. The first edition of the generic standard 50081-1,-2 referred to the 555-2.
1995. IEC published the basic standard 61000-3-2 and CENELEC EN 661000-3-2 with a broader
application range. The basic standard IEC 61000-3-2 supersedes the 555-2 product family standard. The
amendment A12 contains for the user the following important information:
For products that have complied with EN 60555-2 before 01.06.98, as showed by the manufacturer
declaration, this previous EN continues to apply for placing products on the market until 01.01.2001.
All other products described in the scope 61000-3-2, applicable to equipment having an input current up
and including 16 A per phase, and intended to be connected to public low-voltage distribution systems,
must comply from 01.01.2001onwards with 61000-3-2.
1.1 The interference sources of the power line
As a result of increasing non-linearly and non-stationary loads the quality of the power line gets worse. On
the other hand equipment with lower immunity supplied by public power increases. Why the quality of the
public power line gets worse is based on two groups with controversy interest
a) The group of public power line users with low immunity equipment interested in a good power
supply line quality.
b) The group of public power line users with high emitting equipment interested in no emission
reduction because of higher product cost, or lower power consumption.
Between the two groups are the power companies responsible for the power supply quality.

When in the future Electro Magnetic compatibility shall be obtained all three group A to C must do their job.
The Group A must carry out the Immunity tests defined in the immunity basic and product standard to
verify the immunity of the products.
The Group B must carry out the emission measurement defined in the emission standards. The EUT
emission must be below the limits.
The Group C must do some preciousness to fulfil the compatibility levels in the power supply.

The non linear load EUT generates an impulse current I1. Over the resistors R1 a voltage drop in line with
the impulse current occurs. The voltage drop generates a voltage variation at point V1 and V2.. The nonlinear impulse current is an emission of the EUT. For the Harmonics fourier transformation (EFT) this
current is measured.

A lot of loads have automatic turn ON/OFF controls such as thermostats and timers. These types of
controls are included in kitchen appliances, space haters, air conditioners, copiers, ovens, micro wave
ovens, etc. When automatic controls cycle on and off, they cause frequent changes of the load to the
supply.

Lamp
Fig. 1.0.2-2
Voltage variations in low voltage network are generated from cyclical variation of load. The current variation
generates across the power line impedance (impedance between the transformer or generator and the
load) a voltage drop. The voltage drop influences the voltage in the same branch. When loads are
connected at the same branch the r.m.s fluctuation affects the loads. In particular, variation in voltage
amplitude cause change in the light of any filament lamps. Because the output of the filament lamp is
proportional to the square of the applied voltage, changes in light can be significant even for small voltage
variations.
The effect of light Flicker is complex, because it is influenced by the property of the lamp, eye and brain.

1.2 Relevant Standards to HAR1000
1.2.1 Harmonics (Emission) IEC 61000-3-2, EN 61000-3-2
The section of 61000-3-2 is applicable to electric and electronic equipment having an input current up to
and including 16 A per phase, and intended to be connected to public low voltage distribution system. For
system with nominal voltage less then 220 V (line to neutral), the limits have not been considered.
IEC 61000-4-7 Ed. 2.0 b published 2002-08-08
(HAR1000 complies fully with all characteristics required in IEC 61000-3-2)
Electromagnetic compatibility (EMC) - Part 4-7: Testing and measurement techniques - General guide on
harmonics and interharmonics measurements and instrumentation, for power supply systems and
equipment connected thereto
Applies to instrumentation intended for measuring spectral components in the frequency range up to 9 kHz
which are superimposed on the fundamental of the power supply systems at 50 Hz and 60 Hz. For
practical considerations, this standard distinguishes between harmonics, interharmonics and other
components above the harmonic frequency range, up to 9 kHz. Defines the measurement instrumentation
intended for testing individual items of equipment in accordance with emission limits given in certain
standards (for example, harmonic current limits as given in IEC 61000-3-2) as well as for the measurement
of harmonic currents and voltages in actual supply systems.
IEC 61000-3-2 Ed. 2.1 b published 2001-10-18
Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current emissions (equipment
input current <= 16A per phase)
Specifies limits for harmonic current emissions applicable to electrical and electronic equipment having an
input current up to and including 16 A per phase, and intended to be connected to public low-voltage
distribution systems. The tests according to this standard are type tests. Test conditions for particular
equipment are given in annex C. For systems with nominal voltages less than 220 V (line to neutral), the
limits have not yet been considered.

1.2.1.2 Classification of equipment
For the purpose of harmonic current limitation, equipment is classified as follows:
16/122
HAR1000-1P, HAR-EXT1000
1.2.1.3 Differences of the four classes defined for harmonics measurements
The limits of the Class B are 1,5 times the limits of the Class A, because the operation is for portable tools
normally limited to a short time use.
For class C (Lighting equipment) limits are in function of the maximum permissible harmonic current
expressed as a percentage of the input current at the fundamental frequency. The 3rd harmonic is related to
the circuit power factor.
Equipment classification for classes A to C is relatively easy, whereas the classification for class D
equipment is only possible by measurements. The harmonics software includes windows for the
classification measurements.
Class D requirements without A14:
• Equipment with the input current wave shape of each half period - referred to its peak value - is within a
certain envelope.
• active power input between 75 (50) and 600 Watt
• can not be classified as class B or C equipment
• no motor driven tools.
For class D equipment, the limits of harmonic currents are defined for the rated load condition. The
harmonics of the input current shall not exceed the values that can be derived from the limits of class D and
should be within the envelope as showed below. The limits are valid for all applications having an active
input power > 75 W. No limits apply for equipment with an active input power up to and including 75 W.
This lower limit of 75 W will be reduced to 50 W. four years after the implementation date of this standard.

1.2.1.6 Requirements of the harmonic measuring circuit
The impedance of the analyser must be as low as possible. The voltage drop due the input current
(HARMONICS=16 A) must be smaller than 0,15 V.
Harmonic current less than 0,6 % of the input current measured under test conditions, or less than 5 mA
whichever is greater, is disregarded.
Care should be taken that the possible high crest factor (ratio of peak value to r.m.s. value) of the current or
the high value of the fundamental current (supply frequency) as compared to the harmonic current to be
measured, do not produce overload or harmful inter-modulation error signals in the input stages of the
instrument. For a crest factor = 3 and a nominal current of 16 A the measuring circuit should be designed
for minimum 50 A.

1.2.1.7 Requirements to the analysis system
For Compliance Tests in accordance with IEC 61000-3-2. at 230 V 50/60 Hz the follows requirements are
given for the measuring of DFT (Discrete Fourier Transform):
• Windows width of 16 cycles of the fundamental frequency must be used for the DFT
• There shall be no gap, and no overlapping between successive measuring windows
• Fluctuating harmonic shall be evaluated by a procedure corresponding to a smoothing of the amplitude
by a low pass filter with a time constant of 1,5 s.
• Accuracy of the measurement 0,2 % of the rated current, or 5 % of the permissible limits whichever is
greater.

equipment are defined in the standard 61000-3-2 as follow:
TV television receivers
Audio amplifier
Video recorders
Different lamps
Vacuum cleaners
Washing machines
Microwave ovens
Induction hobs
Information technology equipment (ITE)
The standard differs between two types of harmonic producing equipment:
• constant or steady state harmonic
• fluctuating harmonic
The most part of products connected to the public power supply generate fluctuating harmonic. These are
loads with different operating mode. A typical example is a photo copier.
For the fluctuating harmonic two limits are defined: odd 2 to 10 and even 3 to 19 up to 1,5 1,5 times the
limits are allowed for each harmonic during a maximum of 10 % of any observation period of 2,5 minutes
The equipment is tested as presented by the manufacturer. Preliminary operation of motors drives by the
manufacturer may needed before the tests are undertaken to ensure that results correspond with normal
use.
One Example of EN61000-3-2
Microwave oven
• The microwave oven must be tested with 100 % nominal power
• A cylindrical borosilicate glass vessel with a diameter of 190 mm and a maximum material thickness of 3
mm must be used
• The vessel must be filled with potable water of 1000 grams ±50
• The load must be placed at the centre of the shelf.
• Turn on the microwave oven a carry out the measurement.
Test condition for other equipment will be given as required. Please ask IEC for further specification of
equipment operating.

1.2.2 Flicker measurement IEC 61000-3-3
The standard 61000-3-3 is applicable to electric and electronic equipment having an input current up to and
including 16 A per phase and intended to be connected to public low-voltage distribution systems of
between 220 V and 250 V at 50 Hz line to neutral. For systems with nominal voltages less than 220 V, line
to neutral and/or frequency of 60 Hz, the limits and reverence values have not yet been considered.

Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques - Section 15:
Flickermeter - Functional and design specifications
Gives a functional and design specification for flicker measuring apparatus intended to indicate the correct
flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable
such an instrument to be constructed. A method is given for the evaluation of flicker severity on the basis of
the output of flickermeters complying with this standard.

Electromagnetic compatibility (EMC) - Part 3-3: Limits - Limitation of voltage changes, voltage fluctuations
and flicker in public low-voltage supply systems, for equipment with rated current <= 16 A per phase and
not subject to conditional connection
This section of IEC 61000-3 is concerned with the limitation of voltage fluctuations and flicker impressed on
the public low-voltage system. It specifies limits of voltage changes which may be produced by an
equipment tested under specified conditions and gives guidance on methods of assessment. This section
is applicable to electrical and electronic equipment having an input current up to and including 16 A per
phase and intended to be connected to public low-voltage distribution systems of between 220 V and 250 V
at 50 Hz line to neutral. This publication supersedes IEC 60555-3.
1.2.2.1 Limits of IEC 61000-3-3, EN 61000-3-3
The standards IEC 61000-3-3 and EN 61000-3-3 define the measurement requirements and the Flicker
limits. The Fig. below shows the voltage change characteristics. The voltage changes are in function of the
repetition of the voltage variation. The graph illustrate that the disturbance can be low at high voltage
amplitude variation and low repetition variation amplitude and can be high at low voltage amplitude
variation and higher repetition.

The curve of diagram is based on tests with a number of persons. The persons have watched a 60 Watt
lamp. When 50 % of the persons felt influenced at a certain voltage variation and repetition rate the point
was drawn in the diagram..
Above the curve more than 50 % of the persons felt influenced. The curve is the limits for flicker
measurement.
Considering this curve a Flicker meter has been defined.. The requirements and the function of a Flicker
meter are defined in the IEC publication IEC 868. The Flicker meter simulates the series „lamp - eye brain). In the past analogue Flicker meter has been build. Today the Flicker meter can be realised by
software and digital signal measurement.

1.2.2.3 Calculation of Pst and Plt
The measure of severity based on an observation period t = 10 minutes is designated Pst and is derived
from the time-at-levels statistics obtained from the level classifier in block 5 on the Flicker meter. The
following formula is use:.
Pst = 0,0314 P0,1 + 0,0525 P1s + 0,0657 P3s + 0,28 P10s + 0,08 P50s
where P0,1 ......to P50 are the Flicker level exceeded for x% of the time during the observation period.. The
suffix „s“ in the formula indicates that the smoothed value should be used, these are obtained using the
following equations:
At a constant Flicker of 1.0 the Pst is 0,72.
P50s =
P10s =
P3s =
P1s =
(P

+ P50 + P80 )

)

+ P1 + P1,5
)

The 0,3 memory time constant in the Flicker meter ensures that P0,1 cannot change abruptly and no
smoothing is needed for this percentile.
The long term flicker Plt, shall be derived from the short term flicker Pst, over an appropriate period related
to the duty cycle of the load, using the following formula:

3 Mechanical structure
3.1 General
The HAR1000 is ideal for running tests in development/test laboratory environments and for outdoor
service on larger systems. For outdoor service, the HAR1000 can be fitted into a military case.
Fig. 3.1-1
The power connections of the HAR1000 and the EUT are located on the rear panel. With the power inputs
on the rear side and the outputs on the front side an optimum de-coupling is guaranteed. This arrangement
allows test set-up without parallel-running cables.
For operation with the TRA1000 or with the HAEXT1000 three phase extension, the power connections are
located at the rear panel of the HAR1000.
The HAR1000 is available with different options:
Standard with handle as showed in Fig. 3.1. This version is recommended for use in development and
EMC test laboratories.
19“ insert version. The handle is removed and angle brakees are fixed on both sides for fixing the

6.2.2 Harmonics measurements „Detailed“
To get reproducible measuring values check the follows:
• Fulfils the source the condition in accordance with IEC 61000-3-2 „clean sinusoidal power voltage“?
• The correct current range is selected? The measuring circuit shows not overflow?
• Is the operation condition clear defined for the measurement?
6.2.3 Check of the supply generator
Fig. 6.2.2.1-1
The requirements of the EUT power voltage are given in the chapter 1.1.1.5 . The requirements are
continuously checked. As long as the HAR1000 EUT power voltage is within the tolerances it will be
indicated with „EUT-Power ON“ in green colour. When the EUT power voltage is out of the specification it
will be indicated with „Out of Spec“ in red colour.
Fig. 6.2.2.1-2
At any time the public power line voltage can be checked and the harmonic analysis can be made as
follow:
• Turn off the amplifier.
• Select voltage in frequency and time domain
• Change to the measuring windows
• Turn on the public power line
• Zoom resolution until the voltage amplitude of the harmonic are visible
• When the measurement is turned on, the voltage amplitude of the harmonic will be registered.
When you turn on the amplifier the display change from „out of spec“ to EUT Power EIN.
60/122
HAR1000-1P, HAR-EXT1000
6.2.4 Selection of the current measuring range
The analysis of the harmonic is based on the current measurement. When the current measuring range
shows overflow the measured and analysed harmonic will be wrong.
When the auto range is selected, automatically the ranges are switched. When a EUT has a fluctuating
current consumption the current ranges switches regularly and therefor the accuracy. The measuring
values will therefore change with the current range switching.
EMC PARTNER recommends to select one range for one measurement. The range for the maximum
current flow must be selected.
The conditions for the measurement are described in the chapter 1.1.1.6.
Additionally for fluctuating harmonic the 1,5 sec filter must be turned on. The filters smooth the peak
amplitude of the fluctuating harmonic. (similar a pointer meter damping). The display will be stabilised.

HAR1000-1P, HAR-EXT1000
6.2.5 Measurements of harmonic
Fig. 6.2.2.3-1
Basically two different windows are available for the indication of the measuring results: the table and the
graph. Both windows show the actual measured and analysed values. Therefore on line information before
test end are displayed. Considering the real time measurement, analysis of the operation condition of the
EUT can be made.
Additionally to the harmonic values other values are indicated as: Urms, Irms, Ipeak, crest-factor (Ratio
peak current to r.m.s. current ), power consumption, power factor and THD for voltage and current.

For the graphic display normalised harmonic values are necessary. The difference between the
representation „linearly and normalised“ is showed in the next Fig.s. In linearly representation the
harmonics and limits are scaled in A. This representation has the disadvantage that harmonic amplitudes of
high order are not visible. By amplitude zooming either at low order or at high order the harmonics are
63/122
HAR1000-1P, HAR-EXT1000
visible. In normalised representation the harmonic amplitudes are displayed in percentage of the limits. The
amplitudes of the different harmonic orders are defined as 100%. For high order harmonics e.g. 40 the limit
of the class A is 46 mA.

6.2.6 Protocol of the measuring results
The Harmonics test system contains different possibilities for the reporting. A fast report can be made by
printing the actual results on a printer. At the different windows are printer symbols available. When the
table windows are open the print out is a table and when the graph windows are open the print out is a
graph.
a) Print in graph mode
b) Print in table mode
c) Print as selected in „Setting“
under protocol.
Fig. 6.2.2.4-1
On the next page the „Protocol Setting Windows“ is copied. On top it can be selected how the protocol
should be printed either in graph or table form. When both forms are selected graph and table will be
printed. Under destination it can be selected whether the protocol should be printed by the printer or into a
file.
As explained later additional programs can be activated i.e. Excel. Automatically the Excel program is
started and the measuring values transferred.
64/122
HAR1000-1P, HAR-EXT1000
At the lower part of the windows the different values for the report can be selected.
When all values and parameter are selected close the windows with „OK“ .
The follow two examples shows the possibilities. The measuring values for the print will be actualised with
the printer symbol Fig. 6.2.3.3-4 c).
Fig. 6.2.2.4-3 Table report
Fig. 6.2.2.4-4 Graph report
As described above the measuring results can be transferred automatically into an other program. The
follow example values transferred into the excel program. The graph on the right hand side shows a graph

HAR1000-1P, HAR-EXT1000
with standard deviation. Other calculations are possible like comparison of measuring results of different
EUT etc.
Fig. 6.2.2.4-5 Link with excel.exe
Fig. 6.2.2.4-6 Example of an Excel document
The top quality report can be reached with a program like WORD. The HARCS program contain examples
with „POT“ (Protocol Oriented Tests). These examples can be used as models.
For a new protocol proceed as follow:
• Open the WORD program
• Open a formatted document with the firm logo etc.
• Place the Cursor where the table or graph should be
• Activate „EMC PARTNER HARCS“. under „Insert“ „Object“ The HARCS program will be placed as
object into the Word document.
• Select all parameter and carry out the measurement.
• When test is over, close the HARCS with the order „Return to document“. Store the Word document
regularly.
• When other test / measurements are needed place further objects into the same document.

6.2.7 Save of the measuring results
Basically all set-ups and measuring results can be saved. The set-ups and the measuring results can be
saved in different files. The saved set-ups have the extension .hsu (Harmonics set-up). With these set-ups
files a library of set-ups can be made i.e. for different line voltage. With the default file the mostly used
power line voltage 230V, current measuring range, test time, etc. can be prepared. Under „File“ - „Open“
and under directory „HARCS“ all set-ups are listed see Fig. below. The file default.hsu contain the EMC
PARTNER standard set-up.
Fig. 6.2.2.5-1 Open set-ups
When a set-up has changed it can be saved with „SAVE“ or Save As“
Fig. 6.2.2.5-2 Save set-ups
The measuring results can be saved as follow:
67/122
HAR1000-1P, HAR-EXT1000
• Carry out the measurement (as long as the measurement is active the Save Report is grey and not
active)
• When the measurement is over save the measuring results with „File“ „Save Report“. The files have the
extension .hrp.
„Save Report“ includes the following windows:
a) Graph
b) Table
c) Recorder
Fig. 6.2.2.5-4
At a later time all the windows showed above can be opened with „File“ and „Open Report“ and the
measuring results can be analysed.
No measured values ca be lost. At begin of a new measurement automatically a window is opened with
demand to store the report. The operator must take the decision save or destroy the report.
68/122
HAR1000-1P, HAR-EXT1000
6.2.8 Analyses of the saved measuring values with the recorder
Fig. 6.2.2.6-1
During the test all measuring data will be collected from the integrated recorder and stored on the hard disk
of the external PC. With the so stored data after the test end very easy analysis can be made i.e. sequence
of the harmonis over the test time.
Up to eight tracks can be simultaneously displayed in the same windows. For each track the parameter can
be selected from a list (pull down menu) see open windows track 7 in the Fig. above.
The recorder windows can be opened in parallel with the HARCS measuring windows.
The recorder graph can be printed with the printer symbol.
All measuring data are collected, therefor it is not necessary to select the wanted data before carry out the
measurement.

6.2.10 Flicker measurement „In detail“ (Flicker)
Fig. 6.2.4-1
The definition of the different limits is explained in chapter 1.1.2.1. Further in the annexe is a copy of the
drawing with the voltage limits of the IEC 61000-3-3 standard attached.
Fig. 6.2.4-2
71/122
HAR1000-1P, HAR-EXT1000
The cumulative probability diagram can be replaced by the Pst histogram. With this values the short term
flicker is calculated as follow
Pst = 0,314 P0,1 + 0,0525 P1s + 0,0657 P3s + 0,28 P10s + 0,08 P50s
Considering this value it can be decided before test end whether the EUT will fail the flicker test.
The flicker test will be marked as „Running test passed“ when the test time is over.
Additionally to the histogram or the cumulative probability curve a flicker table can be opened with the
calculation of actual flicker, Px value, Pst and Plt..
As for the harmonic measurement the power line voltage measurement results will be continuously
compared with the source limits.
Save of flicker reports, flicker set-ups etc. are equal the description in chapter harmonics

6.2.11 Measurement of the inrush current when the EUT is switched on Manually.
Example Laser-printer
Manual Switching:
"For voltage changes by manual switching, equipment is deemed to comply without further testing if the
maximum r.m.s. input current (including inrush current) evaluated over each half-period between zerocrossings does not exceed 20A, and the supply current after inrush is within a variation band of 1.5A"
Test conditions for measuring dmax voltage changes caused by manual switching:
The considerable variations in the designs and characteristics of manually operated switches cause wide
variations in the results of voltage change measurements. A test procedure dependent on actual operation
of the EUT's manually operated switch is essential. Therefore a statistical method shall be applied to the
measurement of dmax in order to achieve repeatability of test results.
Procedure
a)
24 measurements of inrush current data shall be carried out in the following order:
-- start measurement
-- switch on the EUT (to create a voltage change)
-- let the EUT operate as long as possible under normal operating conditions during a measuring time
interval of one minute,
-- switch off the EUT before the end of the 1 minute interval and make sure that all moving parts inside the
EUT come to standstill before the next measuring interval is started,
-- start the next measurement.
b)
The final test result shall be calculated as follows:
-- delete the highest and lowest result and take the arithmetical average of the remaining 22 values.

6.4 ANASIM Software
The Software can be activated with „Option - Simulation - SIM „ Example Harmonics“
For the time being a lot of equipment does not fulfil the requirements of EN 61000-3-2 of IEC 61000-4-2.
Mostly equipment related to the class D including rectifier generate harmonics over the limits.
When Harmonics measurements has been carried out on hardware and the measurement results over
pass the limits, what can be done? What must be changed in the hardware to get within the limits?
--> The "ANASIM" software will help.
Sequence :
1. Step :
After a practical measurement is over the function Evaluate Values from Measurements will evaluate a
circuit based on the actual current measurement.
2. Step:
The included simulator calculate with the evaluated circuit and component parameter a current wave and
displays the measured and simulated current in the same graph. When the two curve are similar the next
step can be taken
3. Step:
Countermeasure can be checked by changing the component values e.g. serial inductance or damping
resistor etc. The result of a new simulation will be displayed. When the results are within the limits the real
countermeasure can be carried out on the equipment.
For more information see Help file of HARCS-ANASIM Software
78/122
HAR1000-1P, HAR-EXT1000
The Software can be activated with „Option - Simulation - SIM „ Example Flicker“
The "ANASIM" Software with the Flicker simulation offers the possibilities to calculate in advance the
Flicker of a circuit. Today no other software can be found on the market for flicker simulation. The
"ANASIM" software is a sophisticated tools for design and test engineers. The Flicker can not be
analytically calculated.
The basis for the simulation is the input current of the EUT. The current versus time can be written in a
table, see example below or from a input file. With the values of the table the simulator calculate the Flicker
and displays the results in the measuring windows of the HARMONICS-1000.
Source of data : from table
The basis for the simulation is the input current of the EUT.
The edge points of the current waveshape versus time are listed in the table.
(Piece Wise Linear approximation)
The graph beside the table shows in function of the chosen mode either the current versus time or the dtfunction ( voltage versus time after the LIN )
Repeat Sequence repeats the defined sequence till the test time is over.

14.1.1 Examples: harmonic measurements with and without supply generator
EUT: Monitor
EUT: Monitor
The power line voltage is out of the specified limits
of the standard IEC 61000-3-2 see „Voltage out of
Spec“. The power line voltage shows a flat curve
and therefore the current peak and the associated
harmonics are reduced „Incorrect measurement“.
Compare the two Fig.s
With the power amplifier in line the EUT voltage is
within the specified limits for the Harmonics
measurement. The voltage has a sinusoidal wave
form. The positive peak current and therefore the
different Harmonics are strongly increased

14.4.1 Additional Instruction for three phase delta power supply on HAR1000-3P
Instruction to the different elements of the front panel can be found in manual on page 39 and 40.
For the HAR1000-plus additionally information ca be found on page 47/108 for voltage selection and at the
end of the manual the wiring diagram „Deltapower Supply for HARMONICS1000-3P-plus is inserted“.
Voltage setting on the power amplifier for harmonics measurement.
Single phase operation
In the windows „Option“ the 3phase must be deactivated.
In the windows „Setting“ the „Nominal voltage“ must be set to the voltage, as EUT power supply of the
Harmonics is connected to. (Nominal voltage is always the phase to neutral voltage L to N or PE)
Three phase operation
In the windows „Option“ the 3phase must be activated.
In the windows „Setting“ the „Nominal voltage“ must be set to the voltage, as EUT power supply of the
Harmonics is connected to.
106/122
HAR1000-1P, HAR-EXT1000
Nominal voltage is always the phase to neutral voltage L to N or PE. This is independent of EUT
delta or star connection as the source HAR1000-3P-plus is always a star connection
Example 1
tests on EUT must be made with 200 V phase to phase voltage (EUT delta or star not relevant)
Check the public power supply of the HAR1000-plus, see page 47/108 of the manual
The three switches of the front panel must be in the position of 115 V (115V = L-N voltage for 200V L-L..
Calculation of VL-N = VL-L/ 1.732)
In the windows „Setting“ the „Nominal Voltage“ must be set to the voltage, as EUT power supply of the
Harmonics is connected to. (Nominal voltage is always the phase to neutral voltage L to N or PE)
Nominal voltage setting V= 200/1.732 = 115 V
With the green power button the EUT power supply can be turned on.
Between the phases the voltage must be 200 V and between phase and neutral 115 V
The amplifier can correct the power voltage also for VL-L = 220 V or VL-N = 127 - Setting 127V
Caution !
When under setting „Nominal Voltage“ the phase to phase voltage has been selected, the power amplifier
will only amplify to the maximum voltage of about 266 V
Example 2
tests on EUT must be made with 380 V phase to phase voltage (EUT delta or star not relevant)
The three switches of the front panel must be in the position of 230 V (230V = L-N voltage for 380V L-L..
Calculation of VL-N = VL-L/ 1.732)
In the windows „Setting“ the „Nominal Voltage“ must be set to the voltage, as EUT power supply of the
Harmonics is connected to. (Nominal voltage is always the phase to neutral voltage L to N or PE)
Nominal voltage setting V= 380/1.732 = 220 V
With the green power button the EUT power supply can be turned on.
Between the phases the voltage must be 380 V and between phase and neutral 220 V
The amplifier can correct the power voltage also for VL-L = 400 V or VL-N = 230 V -Setting 230V

determining disturbance characteristics of electrical equipment having a rated current = < 75 A
per phase
Published: 2005-05-30
This technical report records the information that was available and the factors that were taken
into account in arriving at the reference impedances that were formerly incorporated in IEC
108/122
HAR1000-1P, HAR-EXT1000
60555, but which are now incorporated into some sections of IEC 61000-3.
In addition, information is given on the impedances of public supply networks associated with
service current capacities >=100 A per phase.
With HARCS Immunity Software the HAR1000 complies with:
14.5.6 IEC 61000-4-13 Ed.1.0
Electromagnetic compatibility (EMC) - Part 4-13: Testing and measurement techniques Harmonics and inter-harmonics including mains signalling at a.c. power port, low frequency
immunity tests
Published 2002-03-27
Defines the immunity test methods and range of recommended basic test levels for electrical and
electronic equipment with rated current up to 16 A per phase at disturbance frequencies up to and
including 2 kHz (for 50 Hz mains) and 2,4 kHz (for 60 Hz mains) for harmonics and interharmonics on low voltage power networks. Establishes a common reference for evaluating the
functional immunity of electrical and electronic equipment when subjected to harmonics and interharmonics and mains signalling frequencies. The test method documented in this part of IEC
61000 describes a consistent method to assess the immunity of an equipment or system against
a defined phenomenon.
