That electromagnetic interference from the analysis of the consequences of the formation of the basic elements of departure. Harassment by the electromagnetic emission of electromagnetic energy sources, transmission channels through coupling to sensitive equipment, a process known as electromagnetic interference effects. Therefore, the formation of the consequences of electromagnetic interference must have three basic elements: e3h Safety and EMC Network
1, electromagnetic interference and electromagnetic compatibility e3h Safety Net
Any form of natural phenomena or power plant fired by electromagnetic energy, can share the same environment, or other biological harm, or to place other equipment, subsystems or systems electromagnetic hazards, resulting in performance degradation or failure, such natural phenomena or power plant that is known as electromagnetic interference source. e3h Safety and EMC Network
2, coupled channels e3h Safety and EMC Network
Electromagnetic coupling means that transmission path or media harassment. e3h Safety and EMC Network
3, sensitive equipment (Victim) e3h Safety and EMC Network
When sensitive equipment is subject to electromagnetic interference source electromagnetic energy emitted by the role, it will hurt the people or other organisms, as well as electromagnetic damage will occur, resulting in performance degradation or failure of the devices, equipment, subsystem or system . Many devices, equipment, subsystem or system can be both electromagnetic
Interference source is sensitive equipment. e3h Safety and EMC Network
Order to achieve electromagnetic compatibility, we must proceed from the three fundamental elements above, the use of both the technical and organizational measures. The so-called technical measures, that is, from the analysis of electromagnetic interference source, coupling means and sensitive equipment set, to take effective technical means to suppress interference source, to eliminate or reduce harassment of the coupling, reducing sensitive equipment or increase the response to the harassment of electromagnetic sensitivity level; as a right to restrict human disturbance, and verify the effectiveness of technical measures used, the measures must be taken to organize, develop and follow a complete set of standards and norms, to a reasonable spectrum allocation, control and management of spectrum use, according to frequency, working hours, provisions for directional antennas work, analysis of electromagnetic environment and select the layout area, for electromagnetic compatibility administration. e3h Safety and EMC Network
Electromagnetic compatibility is Electronic Equipment or one of the main performance, electromagnetic compatibility design requirements to achieve the functions of equipment or system, so that system performance can be an important guarantee for the full play. Equipment or system must be functional design, while electromagnetic compatibility design. e3h Safety and EMC Network
EMC design is intended to provide the design of electronic equipment or system to achieve the expected electromagnetic environment electromagnetic compatibility. The requirement is to make electronic equipment or system to meet the provisions of EMC standards and have both the capacity: e3h Safety and EMC Network
1. Can be expected to work the electromagnetic environment, no performance degradation or failure; e3h Safety and EMC Network
2. Is not a source of pollution of the electromagnetic environment. e3h Safety and EMC Network
To a realization of electromagnetic compatibility, must examine the following five questions: e3h Safety and EMC Network
First, the source of electromagnetic harassment, including harassment of sources of electromagnetic frequency domain and time domain characteristics, resulting in the mechanism and measures of inhibition. e3h Safety and EMC Network
Second, the propagation characteristics of electromagnetic disturbance, or of how the harassment of sources of electromagnetic disturbance spread to the sensitive equipment, including conduction harassment and harassment of radiation. Conduction disturbance is down conductor transmission of electromagnetic disturbance, radiation disturbance from devices, components, cables, cable or antenna, and electromagnetic radiation devices ah system disturbance. e3h Safety and EMC Network
