1 I NTRODUCTION
The Harmonics & Flicker Generator 01 (HFG01) has been designed by York EMC
Services for the purpose of providing an easy and reliable way to externally check
the performance of measurement systems used for testing against the EN/IEC
61000-3-2 harmonics and interharmonics and EN/IEC 61000-3-3 flicker standards.
The HFG01 allows the user to periodically verify their test equipment and its
operation together, helping to ensure compliance with standards and laboratory
quality procedures.
The HFG01 provides a series of harmonic and flicker disturbances of a nominal
but stable level. The HFG01 may therefore be used to verify the stability of a
measurement system. Additionally, due to its own stability it may be used as a
transfer standard from a calibrated system, or be used as a repeatable source of
interference for diagnostic and/or development design work.

HFG01 Operation Manual

2 D ESCRIPTION
The HFG01 simulates equipment under test (EUT), generating known, repeatable
levels of harmonic and flicker disturbance in one of four modes of operation.
The flicker test modes generate a fixed level of mains disturbance at a rate of 1 Hz
and 8.33 Hz. These modes support verification of the test systems used for EUT
flicker disturbance measurements as described in the EN/IEC 61000-3-3 test
standards.
The harmonics test modes are designed to produce a variety of harmonic-rich
current waveforms. These current waveforms support verification of the test
systems used for mains-powered equipment load current testing as described in
the EN/IEC 61000-3-2 test standards.
The HFG01 can be used with test systems operating at 230 Vac (nominal) supply
voltages and 50 Hz supply frequency. Connection to the test system is by a captive
lead pre-fitted with a CEE 7/7 European style plug thatfits directly with power outlet
used by a wide range of harmonics and flicker equipment.
The HFG01 itself is powered by a wide-input range AC/DC power supply unit that
is powered separately from the Test Supply under test. This ensures that the
disturbance signals generated by theHFG01 are not affected by the need to derive
the HFG01’s own supply needs from the Test Supply under test.
For ease of access all connections, user controls, and indicators are located on
the front panel of the HFG01. The HFG01 is supplied with the external power unit
with mains cable, manufacturer’s test certificate, and a CDROM containing digital
copies of the manual, test certificate, and files of the tabulated certificate data.

5.4 Enabling the test
Figure 4: Test Enable switch and indicator
The selected test mode is enabled by pressing the Start Test switch and the
indicator displays the running test status.
5.5 Performing a test.
The HFG01 acts as the equipment under test in the harmonics and flicker test
system, and should be connected to the single-phase test power supply as per the
typical test setup used (Figure 5 for example).
Figure 5: Example of a typical test setup
Connect the HFG01 power supply and turn the HFG01 on by pressing the
power switch . The power supply indicator should be illuminated green to
indicate the HFG01 is operating correctly.
The Test Supply Input cable can be plugged into the Test Supply power output
socket. Note that if the Test Supply does not provide a safety earth connection as
one of the conductors (e.g. 2-pin Live and Neutral only) then the Chassis Earth
wiring stud on the front of the HFG01 must be connected to a suitable earth first
(not shown). A suitable earth point may be provided elsewhere on the Harmonics
and Flicker test system.

HFG01 Operation Manual
York EMC Services Page 14 of 21 Doc. No. Y0321/DOC/038 Rev. 2
Configure the Harmonics and Flicker Test System to measure harmonic or flicker
disturbance as per the system instructions, with the Test Supply configured to
provide the required voltage and frequency.
Once the Test Supply has been safely connected, the Harmonics and Flicker Test
Supply can be enabled.
Select the required test load operation using the Test Mode switch .
The chosen test load operation can be enabled before or after the Harmonics and
Flicker Test System has started the test routine. When ready to enable the load
operation, press the Start Test switch . The Test Enable display should
indicate that the test is running.
Pressing the Start Test switch again will disable the running test. Changing the
Test Mode selection switch will also disable the running test. The new selected
test will need to be started by pressing the Start Test switch again.
Note:
If the HFG01 test has been running for more than 2 hours continuously it is
recommended that it is allowed to cool down before power is finally removed, to
reduce any latent heat build-up. To do this, leave the HFG01 turned on but with no
running test for approximately 10 to 15 minutes before fully powering down.
5.6 Troubleshooting a test
The test load operation will be disabled if the HFG01 detects too many dropped
voltage cycles or interruptions from the Test Supply.
If the HFG01 load exceeds its recommended operating temperature, the test load
operation will be disabled (Test Enable display will be OFF) and the Alarm
indicator will flash at a steady rate. Once the temperature has returned to
normal the Alarm indicator will turn off and the test can be resumed.
If the HFG01 detects asystem error, the Alarm indicator will fully turn on without
flashing. The system error will need to be cleared by removing all power from the
HFG01 before fully restarting. If fully restarting the device fails to clear the error,
the HFG01 may require servicing.
A flowchart for troubleshooting if the test cannot be enabled is shown in Figure 6.
In the case of other problems, please contact your supplier for advice.

6.3 Calibration
The HFG01 is supplied with a manufacturer’s calibration certificate.
It is recommended that the HFG01 should be periodically checked to ensure
damage or long-term changes have not altered the output. The periodicity of these
checks is typically determined by the quality assurance regime employed by the
user, however it is recommended that the HFG01 output be retested annually. This
service is available from York EMC Services and can be arranged through your
supplier.

8 ELECTROMAGNETIC COMPATIBILITY
8.1 General
The HFG01 has been designed to meet the requirements of EU Directive
2014/30/EU. Compliance was demonstrated by testing to the requirements of the
following standards: -
8.2 Emissions
EN61326-1 (2013) consisting of
•EN55011 (2009) + A1 (2010) Radiated RF emissions (Enclosure) and
Conducted RF emissions (applies to the HFG01 supply adapter), Class A
8.3 Immunity
Enclosure:
EN61326-1 (2013) consisting of
•EN61000-4-2 (2009) Electrostatic Discharge immunity, 4 kV Air & Contact
Discharge.
•EN61000-4-3 (2006) + A1 (2008) + A2 (2010) Radiated RF immunity
(Enclosure), 3 V/m.
AC power:
These apply to the HFG01 supply adapter only:
EN61326-1 (2013) consisting of
•EN61000-4-11 (2004) Voltage dips/short interruptions
•EN61000-4-4 (2004) + A1 (2010) Fast Transient common mode (AC mains
port)
•EN61000-4-5 (2006) Surge (AC mains port)
•EN61000-4-6 (2009) Conducted RF immunity (AC mains port)
•EN61000-3-2 (2006) Harmonic emission (AC mains port)
•EN61000-3-3 (2013) Voltage fluctuation (AC mains port)
8.4 Non-Applicability
EN61326-1 (2013) consisting of
•EN61000-4-4 (2004) Fast Transient common mode (signal ports)
•EN61000-4-5 (2006) Surge (signal ports)
•EN61000-4-6 (2009) Conducted RF immunity (signal ports)
These phenomena are deemed non applicable on the basis that the HFG01 has
no relevant signal ports. The AC test port of the HFG01 may be looked upon as a
signal port but the captive lead is less than 3m in length hence the tests do not
apply.
The test port is not connected directly to the public low voltage supply network and
so tests relating to AC ports are only applicable to the AC/DC adapter used for the
HFG01 supply input.
