The hazards of electromagnetic interference are:
Hazardous to human health, such as ultraviolet rays in the sunlight, which can make the skin cancerous; X-rays, gamma rays will destroy the molecular structure of the human body, causing a variety of cancers.
Interference with the normal work of communication equipment such as communications, radio, television, etc. According to the electromagnetic induction of the original financial, all electric and magnetic conductors are the object of its induction interference.
May ignite some flammable and explosive substances, causing explosions and fires, electromagnetic interference caused by some of the electronic supplies heating and burning or even exploding and causing fires.
How to prevent electromagnetic interference
Shielding: that is, to the source of the interference to make a metal jacket, the source of the interference can be covered up.
Filtering: Selection of reactors, filters, filtering magnetic rings and other devices, installed on the power supply of the interference source.
Grounding: give the interference source to do a standard grounding.
