Electromagnetic disturbances can affect the normal operation of various electrical and electronic components within an electrical panel leading to loss of data, incapability of the component or device to perform its intended function and also degradation in the performance of the entire system. To minimize the effects of electromagnetic disturbances, noise reduction techniques should be integrated at the design stage. The paper focuses on building electrical panels that are complaint to electromagnetic compatibility. This paper provides an introduction to the noise sources and coupling paths of electromagnetic interference that are commonly found in a large automated system. Also, noise reduction techniques are discussed in this paper.
