材料及設備問題
接入DCS系統(tǒng)的控制信號通常采用電纜作為傳輸介質將信號送至DCS系統(tǒng)，當信號電纜絕緣材料老化，屏蔽材質損壞，即會被其他電磁干擾源干擾，干擾會造成測量的誤差，嚴重的干擾會造成設備損壞。
施工不規(guī)范
在DCS控制系統(tǒng)中，往往有很多信號同時接入DCS。這些信號線或者走電纜槽，或者走電纜管，造成現(xiàn)場很多不同種類電纜在同一個路徑附設。這些信號之間均有分布電容存在，會通過這些分布電容將干擾加到別的信號線上。同時，在傳輸信號的周圍環(huán)境產(chǎn)生交變的磁通，例如動力線、電動機、發(fā)電機、電源變壓器和繼電器等都會產(chǎn)生這種磁場。這些磁場往往會造成較大的干擾。
接地不合理
比較常見的接地事故是信號線的兩端均接地，這樣會因地電勢差而產(chǎn)生較大的干擾。如信號線的兩端同時接地，可能會有較大的電位差，這種電位差可能會在兩端之間的信號線上產(chǎn)生一個很大的環(huán)流。產(chǎn)生電磁波，干擾信號。還有DCS系統(tǒng)總接地電阻不符合DCS系統(tǒng)正常工作要求等等。
