EMC Technologies high-power flicker, harmonics and power quality compliance testing

The European Union (EU) requires electrical products to comply with a series of CE marking EMC standards relating to power quality. These include harmonics, flicker and inter-harmonics immunity standards. Harmonised standards are used to declare compliance against the EMC Directive 2014/30/EU, the Radio Equipment Directive 2014/53/EU and the Low Voltage Directive (LVD) 2014/35/EU.

EMC Technologies’ Melbourne laboratories have recently commissioned a sophisticated high-power full compliance test system that tests single- and three-phase electrical equipment at up to 75 A per phase, plus full compliance testing to a range of non-mandatory power quality AC and DC immunity standards. The system also provides compliance testing to the power quality requirements of Australian energy authorities for air conditioners and other domestic/residential equipment up to 75 A per phase.

The system meets IEC 61000-4-7 sampling rate and resolution requirements and provides arbitrary waveform generation, precision measurements and waveform analysis. The Flicker reference impedance IEC 868 complies up to 75 A per phase.

The system software supports a test file replay mode, which permits the viewing of both harmonics and flicker tests as if they are performed in real time. Complete test reports are generated automatically.

EMC Technologies also provides NATA ISO 17025 calibration of flicker and harmonics measurement systems per EN 61000-3-2 and EN 61000-3-3.
