UpcomingElectromagnetic compatibility-Limits—Part 8: Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16 A and ≤75 A per phase
电磁兼容 限值 第8部分：每相输入电流大于16A小于或等于75A连接到公用低压系统的设备产生的谐波电流限值
Application Summary AI generated
This standard specifies the limits for harmonic currents injected into public low-voltage AC power systems (typically 220/380V, 50Hz) by equipment drawing between 16A and 75A per phase. It is applied to industrial and commercial electrical devices, such as large HVAC units, industrial machinery, and high-power lighting systems, to ensure they do not cause excessive voltage distortion that could disrupt other users on the same grid. Compliance testing under this standard is mandatory for equipment sold in China to meet electromagnetic compatibility (EMC) regulations.
