GB 17625.1-2022 Electromagnetic compatibility—Limits—Part 1:Limits for harmonic current emissions(equipment input current ≤16 A per phase)
Basic Information
Scope
This document specifies the limits for harmonic currents injected into the public power supply system.
This document stipulates the limits for the harmonic components of the input current that equipment may generate under specified test conditions.
This document applies to electrical and electronic equipment with a rated input current of no more than 16 A per phase that is intended to be connected to the public low-voltage distribution system.
Non-dedicated arc welding equipment with a rated input current of no more than 16 A per phase falls within the scope of this document. All other arc welding equipment is not applicable to this document; however, its harmonic current emissions can be evaluated using IEC 61000-3-12 and related installation restrictions.
The tests conducted in accordance with this document are type tests.
For systems with a nominal voltage lower than 220 V (phase voltage), the limits have not been taken into account yet.
Note: In this document, terms such as devices, appliances, components, and equipment are used, and they all have the same meaning in this document.
