EMC Technologies power quality standards testing

EMC Technologies now provides NATA accredited testing to Power Quality standards EN/IEC 61000-3-2 and EN/IEC 61000-3-3 including the AS/NZS equivalents.

The facility also now provides the internationally accepted ISO 17025 NATA accreditation for the calibration of Harmonics and Flicker (H&F) compliance test systems used to measure H&F in per IEC/EN/AS/NZS 61000-3-2 and 61000-3-3.

Accredited calibration of H&F test systems was only previously possible in overseas calibration labs, which was made difficult as shipping test systems can be prohibitively expensive.

Major inconsistencies in the interpretation of the calibration procedures also posed problems, as many calibration labs ignored the Power Source of the H&F test system and excluded it from the calibration. Two new standards (IEC Technical Reports) have been published to regulate calibration methods:

• IEC TR 61000-4-37:2016 Calibration and verification protocol for harmonic emission compliance test systems.
• IEC TR 61000-4-38:2015 Test, verification and calibration protocol for voltage fluctuation and flicker test systems.

Calibration and testing can also be carried out on-site at customers’ premises.

Compliance with Harmonics and Flicker standards is mandatory for CE Marking and for certification of energy-savings products under various energy regulator schemes in Australia and overseas.
