In addition to the intentionally produced electromagnetic energy, there are some devices producing radiation, such as welding, thyristor devices, fluorescent lamps, inductive load Switching operation. This interference performance for conducted interference in most cases, conducted interference in other IEC 61000-4 series of standards Section involved. A method for preventing the influence of electromagnetic fields will often reduce the impact of such interference sources. Electromagnetic field strength in the environment depending on the environment. Because of the surrounding buildings and near other devices causes reflection of electromagnetic waves And/or distortion, if there is no advanced equipment, the field strength is difficult to measure, it is difficult to classical formulas or equations to calculate. 5 test levels
