空間的輻射電磁場(chǎng)（EMI）主要是由電力網(wǎng)絡(luò)、電氣設(shè)備的暫態(tài)過程、雷電、無線電廣播、電視、雷達(dá)、高頻感應(yīng)加熱設(shè)備等產(chǎn)生的，通常稱為輻射干擾，其分布較為復(fù)雜。若PLC系統(tǒng)置于所射頻場(chǎng)內(nèi)，就回收到輻射干擾，其影響主要通過兩條路徑：一是直接對(duì)PLC內(nèi)部的輻射，由電路感應(yīng)產(chǎn)生干擾；而是對(duì)PLC通信內(nèi)網(wǎng)絡(luò)的輻射，由通信線路的感應(yīng)引入干擾。輻射干擾與現(xiàn)場(chǎng)設(shè)備布置及設(shè)備所產(chǎn)生的電磁場(chǎng)大小，特別是頻率有關(guān)，一般通過設(shè)置屏蔽電纜和PLC局部屏蔽及高壓泄放元件進(jìn)行保護(hù)。
