GB/T 17626.19-2022
ActiveElectromagnetic compatibility—Testing and measurement techniques—Part 19: Test for immunity to conducted, differential mode disturbances and signalling in the frequency range 2 kHz to 150 kHz at a.c. power ports
电磁兼容 试验和测量技术 第19部分：交流电源端口2kHz~150kHz差模传导骚扰和通信信号抗扰度试验
Application Summary AI generated
This standard specifies the immunity test method for electrical and electronic equipment against conducted, differential mode disturbances and communication signals in the 2 kHz to 150 kHz frequency range applied at AC power ports. It is primarily used in the electromagnetic compatibility (EMC) testing of equipment connected to low-voltage public or industrial AC power networks, such as power line communication (PLC) devices, smart meters, and industrial controllers. The standard ensures that equipment can withstand interference from power line signaling and harmonics without performance degradation.
