ActiveElectromagnetic compatibility—General—Historical rationale for the limitation of power-frequency conducted harmonic current emissions from equipment, in the frequency range up to 2 kHz
电磁兼容 综述 2kHz内限制设备工频谐波电流传导发射的历史依据
Application Summary AI generated
This standard provides the historical and technical rationale behind the limits for low-frequency harmonic currents (up to 2 kHz) emitted by electrical and electronic equipment. It is applied in electromagnetic compatibility (EMC) testing and product design to ensure that devices connected to public low-voltage power grids do not cause excessive harmonic distortion. The standard is primarily used by engineers and regulators in the telecommunications, consumer electronics, and industrial equipment sectors to understand the basis for compliance requirements.
