Harmonic and Flicker Generator 01
The Harmonics & Flicker Generator (HFG01) has been designed for the purpose of verifying harmonic and flicker test equipment.
The HFG01 provides an easy and reliable way to externally check the performance of the measurement system to the IEC/EN 61000-3-2 harmonics and IEC/EN 61000-3-3 flicker standards; particularly important as these tests rely on software control and calculation, and for which there is no intuitive sense of the response.
The HFG01 provides a series of harmonic and flicker disturbances of a nominal but stable level. This allows the user to periodically verify their test equipment, helping maintain compliance with standards and laboratory quality procedures. Alternatively, due to its stability, it may be used as a transfer standard from a known, calibrated test system.
The HFG01 is a standalone device and requires no additional equipment. It connects directly to the test equipment and simulates the equipment under test (EUT), generating known, repeatable levels of harmonic and flicker disturbance.
