GB/T 18039.4-2017
ActiveElectromagnetic compatibility—Environment—Compatibility levels in industrial plants for low-frequency conducted disturbances
电磁兼容 环境 工厂低频传导骚扰的兼容水平
Application Summary AI generated
This standard specifies acceptable compatibility levels for low-frequency conducted disturbances, such as harmonics, interharmonics, and voltage fluctuations, in industrial power supply systems. It is applied by engineers and manufacturers to ensure electromagnetic compatibility (EMC) between electrical equipment and the industrial plant environment, preventing performance degradation or malfunction. The standard is used in the design, testing, and assessment of industrial facilities and their connected devices, particularly within factory settings where heavy machinery and variable loads are common.
