ActiveElectromagnetic compatibility - Environment - Compatibility levels for low-frequency conducted disturbances and signaling in public medium-voltage power supply systems
电磁兼容 环境 公用中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 specifies compatibility levels for low-frequency conducted disturbances and signaling in public medium-voltage power supply systems, typically ranging from 1 kV to 35 kV. It is applied by power utilities and equipment manufacturers to ensure electromagnetic compatibility between the power network and connected devices, particularly in industrial and commercial environments where sensitive electronic equipment shares the grid. The standard helps define acceptable limits for voltage fluctuations, harmonics, and signaling interference to prevent malfunctions in telecom and power distribution systems.
