The new Harmonics & Flicker Generator (HFG02) is Eurofins York newest HFG product. It is a multi-function electronic load which has been designed with the purpose of verifying harmonic and flicker test equipment. It 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.

FEATURES

Stable load simulation

• Repeatable measurements for test system verification
• Injects harmonics to EN61000-3-2 and flicker to EN61000-3-3

– Evaluation of test systems specifically to EN standards

• • Harmonic test modes

– Steady-state harmonic-rich load current, representing a fixed load

• – Harmonic-rich load currents fluctuating between two load conditions
• – Interharmonic load currents at 5 Hz and 10 Hz rates

– Harmonic and interharmonic-rich load

• • Flicker test modes
• – Fixed level of mains disturbance at 1 Hz rate
• – Fixed level of mains disturbance at 8.33 Hz (50 Hz supply) or 8.6 Hz rates (60 Hz supply)

• • EUT modes

– Simulates waveforms generated by several different types of equipment:

• – – Half-wave rectifier
• – – Analogue dimmer
• – – Intermittent flicker

• • Compact and Portable

– Comparisons between multi-site test environments

• • Dual supply operation
• – Automatically detects 115 Vac and 230 Vac systems and adjusts its output to match
• – Test supply voltage and frequency indication

• • Independent power supply
• – Separate power supply to the HFG02 to avoid contamination of the test signals
