ELECTROMAGNETIC COMPATIBILITY (EMC) – PART 2-12: ENVIRONMENT – COMPATIBILITY LEVELS FOR LOW-FREQUENCY CONDUCTED DISTURBANCES AND SIGNALLING IN PUBLIC MEDIUM-VOLTAGE POWER SUPPLY SYSTEMS (IEC 61000-2-12:2003, IDT)
This Malaysian Standard deals with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public medium voltage a.c. distribution systems having a nominal voltage between 1 kV and 35 kV and a nominal frequency of 50 Hz or 60 Hz (see IEC 60038).
Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public medium voltage power supply systems, for guidance in:
a) the limits to be set for disturbance emission into public power supply systems (including the planning levels defined in 3.1.5);
b) the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems.
