GB 17625.1-2012 Electromagnetic compatibility—Limits—Limits for harmonic current emissions(equipment input current ≤16 A per phase)
Basic Information
Scope
This section concerns the limitation of harmonic currents injected into the public power supply system.
This section specifies the limits of the harmonic components of the input current that equipment may generate under specified test conditions.
The harmonic components are measured in accordance with Appendices A and B.
This section applies to electrical and electronic equipment with an input current of no more than 16 A per phase, which is intended to be connected to the public low-voltage distribution system.
Non-dedicated arc welding equipment with an input current of no more than 16 A per phase falls within the scope of this section.
The relevant provisions for dedicated arc welding equipment are given in IEC 60974-1, and this section does not address them. Installation restrictions can be referred to in IEC/TR 61000-3-4 or IEC 61000-3-12.
The tests conducted in accordance with this section are type tests. The test conditions for special equipment are given in Appendix C.
The limits for systems with a nominal voltage of less than 220 V (phase voltage) have not been considered yet.
