Electromagnetic Compatibility (EMC) - Part 2: Environment - Section 1: Description of the Environment -Electromagnetic Environment for Low-Frequency Conducted Disturbances and Signalling in Public Power Supply Systems
Scope:
This section of IEC 1000-2 is concerned with conducted disturbances in the frequency range up to 10 kHz with an exten sion 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 parameters, such as its impedance as a function of frequency, have also to be considered. Furthermore, it does not prejudge the specification of immunity levels by the product committees but merely provides a guide.
The disturbance phenomena considered are:
- harmonics;
- inter-harmonics;
- voltage fluctuations;
- voltage dips and short supply interruptions;
- voltage unbalance;
- mains signalling;
- power frequency variation;
- d.c. components.
The object of this section is to give information on the various types of disturbances that can be expected on public power supply systems. It is a reference document for those associated parts that give values of compatibility level.
