Guide to electromagnetic environment for low-frequency conducted disturbances and signalling in public power supply systems Ingestion-build-221493 Tolerances for the plain limit1 Scope This section of IEC 10002 is concerned with conducted disturbances in the frequency range up to 10 kHz with an extension for mains signalling systems. Separate sections give numerical compatibility levels for different system voltage levels. This section does not deal with the application of compatibility levels to assess, for example, the permissible interference emission from specific items of equipment or installations, because other system
