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 that fits 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 the HFG01 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.
