GB/T 17625.9-2016 Electromagnetic compatibility—Limits—Signalling on low-voltage electrical installations—Emission levels,frequency bands and electromagnetic disturbance levels
Abstract
This part applies to electrical equipment that uses signals in the frequency range of 3 kHz to 525 kHz to transmit information on low-voltage electrical installations, which include both public power supply systems and user buildings.
This part specifies the frequency band, the limit values of the terminal output voltage within the operating frequency band, and the limits of conducted and radiated interference for different application scenarios (where applicable), and also provides measurement methods.
This part specifies the interference limits from 3 kHz to 400 GHz.
This part does not specify the modulation method, encoding method, and functional characteristics of the signal.
This part does not include environmental requirements and tests.
