EMI/EMC ( Electromagnetic Compatibility / Electromagnetic Interference)
Technical evaluations in building up advanced infrastructure , Transportation and other utilities have led to increased concentration of electrical and electronic components in steadily decreasing spaces. At the same time, switching frequencies of controllers and power devices are increasing. This increases the risk of mutual interference and associated functional problems in such environment. Electromagnetic disturbance generated should not exceed a level that disturbs radio, telecommunications, and other apparatus.
To ensure proper functionality of modern equipment it is necessary to have EM compatibility.
