Electromagnetic Compatibility (EMC) - Part 3: Limits - Section 8: Signalling on Low-Voltage Electrical Installations - Emission Levels, Frequency Bands and Electromagnetic Disturbance Levels
|Publication Date:||1 August 1997|
|ICS Code (Electromagnetic compatibility (EMC)):||33.100|
This section of IEC 61000-3 applies to electrical equipment using signals in the frequency range from 3 kHz up to 525 kHz to transmit information on low-voltage electrical installations, either on the public supply system or within customers' premises.
It specifies frequency bands allocated to different applications (where appropriate), limits for the terminal output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement.
It specifies disturbance limits in the frequency range from 3 kHz up to 400 GHz.
It does not specify the signal modulation methods nor the coding methods, nor functional features.
Environmental requirements and tests are not included.
NOTE - Compliance with this standard does not imply permission to establish communications with locations outside the customer's installation or with other customers through the public supply system where this would otherwise not be allowed.
