Harmonic Current Emissions Test Standard in accordance with IEC 61000-3-2

The IEC 61000-3-2 standard addresses the limitations of harmonic currents injected into the public supply system. The IEC 61000-3-2 test standard specifies the limits of the harmonic components of the input current that can be produced by the equipment under test under specified conditions.

Harmonic Current Emissions Test Standard in accordance with IEC 61000-3-2

IEC-61000-3-2 is applicable to electrical and electronic equipment having an input current of up to and including 16 A per phase and intended for connection to general low voltage distribution systems. Non-professional arc welding equipment with input current up to 16 A per phase is included in the IEC 61000-3-2 test and EN 61000-3-2 test. Arc welding equipment for professional use as specified in IEC 60974-1 is outside the IEC61000-3-2 test.

May be subject to installation restrictions as specified in IEC 61000-3-12. According to this document, tests are type tests. Limits have not yet been taken into account for systems with rated voltages less than, but not equal to, 220 V (line to neutral). The tests performed according to this standard are type tests.

The purpose of the EN 61000-3-2 standard is to set limits for harmonic emissions of the equipment within its scope, so that compliance with the limits, with the required permit for emissions from other equipment, ensures that harmonic distortion levels do not exceed defined compliance levels.
