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 standard. Harmonised standards are used to declare compliance against the EMC Directive 2014/30/EU, the Radio Equipment Directive2014/53/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 Amps 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 amps per phase.

The CE Marking mandatory standards for power quality are:

EN61000-3-2 harmonics to 16 Amps per phase.

EN61000-3-3 flicker to 16 Amps per phase 

EN61000-3-11 flicker to 75 Amps per phase

EN61000-3-12 harmonics to 75 Amps per phase. 

EN61000-4-11 AC Voltage Dips and Interruptions up to 16 Amps per phase

EN 61000-4-34 AC Voltage Dips and Interruptions, variations with input current more than 16 Amps per phase.

EN61000-4-13 immunity to harmonics and inter-harmonics to 16 Amps per phase. 

These are called up in product standards:

EN61000-4-14 AC Voltage fluctuations

EN61000-4-17 DC Ripple

EN61000-4-27 Three Phase AC Voltage Unbalance

EN61000-4-28 Frequency variations

EN61000-4-29 DC Voltage Dips and Interruptions

DO160 and MIL-STD 704 avionics power immunity.

MIL-STD 1399 Naval power specification

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

 The following immunity tests are also provided by EMC Technologies:

EN 61000-4-10 – Damped Oscillatory Magnetic Field Immunity Test

EN61000-4-12  – Oscillatory Waves Immunity Test

EN 61000-4-16 – Immunity to conducted, common mode disturbances, 0 Hz to 150 kHz.

EN61000-4-17 – Ripple on DC. input power port immunity test

EN 61000-4-18 – NATA- Damped (Fast) oscillatory wave immunity test

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