GB/T 18039.3-2017
ActiveElectromagnetic compatibility—Environment—Compatibility levels for low-frequency conducted disturbances and signalling in public low-voltage power supply systems
电磁兼容 环境 公用低压供电系统低频传导骚扰及信号传输的兼容水平
Application Summary AI generated
This standard defines acceptable levels of low-frequency electromagnetic disturbances, such as harmonics, voltage fluctuations, and signaling voltages, within public low-voltage power supply systems (up to 1 kV). It is applied by utility companies, equipment manufacturers, and testing laboratories to ensure that electrical and electronic devices connected to the grid do not cause or suffer from unacceptable interference. The standard is specifically used in the design, compliance testing, and grid management of household, commercial, and light industrial installations.
