Harmonics and Flicker Generator 02
The new Harmonics & Flicker Generator (HFG02) is our newest HFG product. It is a multi-function electronic load which has been designed with the purpose of verifying harmonic and flicker test equipment.
The HFG02 offers an easy and reliable way to externally check the performance of the measurement system to the EN/IEC 61000-3-2 harmonics and IEC/EN 61000-3-3 flicker standards. A reference source is particularly useful where there is little intuitive sense of the expected response and the tests rely on software control and calculation to produce a result.
The HFG02 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 HFG02 is a standalone device that connects directly to the test equipment and simulates it under test (EUT), generating known repeatable levels of harmonic and flicker disturbance.
