style="text-indent:25px">數(shù)顯儀表產(chǎn)生干擾的途徑：信號(hào)源與儀表之間的導(dǎo)線、內(nèi)部配線通過磁耦合在電路中形成干擾。在大功率變壓器、交流電機(jī)、電力線的周圍空間都存在有很強(qiáng)的交流磁場，而閉合回路處在這種變化的磁場中將產(chǎn)生電動(dòng)勢。這種感應(yīng)電勢與有用信號(hào)串聯(lián)，當(dāng)傳感器與數(shù)顯表距離較遠(yuǎn)時(shí)，這種串模干擾特別突出。干擾源通過電容的耦合在回路中形成干擾，是由于兩電場相互作用的結(jié)果。通過靜電耦合的方式，能在兩輸入端感應(yīng)出對(duì)地的共同電壓，以共模干擾的形式出現(xiàn)，由于共模干擾不和信號(hào)相疊加，它不直接對(duì)儀表產(chǎn)生影響。但它能通過測量系統(tǒng)形成到地的泄漏電流，該泄漏電流通過電阻的耦合就能直接作用于儀表而產(chǎn)生干擾。電磁感應(yīng)、靜電感應(yīng)所形成大多是工頻干擾電壓，但變頻器、帶整流子的電機(jī)等會(huì)產(chǎn)生諧波干擾。</p><p style="text-indent:25px">常見問題：加信號(hào)無反應(yīng) 可能原因：信號(hào)未輸入儀表解決方法：測試儀表接線端子有無信號(hào)，端子連接是否可靠。常見問題：三相儀表缺相可能原因：信號(hào)未加到儀表上解決方法：測試接線端子有無輸入信號(hào)，端子是否正確可靠連接;可將正常顯示的一相信號(hào)線接到缺相信號(hào)進(jìn)行對(duì)比測試。常見問題：電能計(jì)量不準(zhǔn) 可能原因：變比不對(duì)，電壓電流的相序錯(cuò)誤解決方法：將儀表設(shè)置的變比與PT、CT的變比核對(duì)是否一致;檢查電壓、電流的相序是否正確;在用電情況下，有功率顯示的儀表可以通過儀表的功率顯示查看單相功率是否有負(fù)號(hào)指示，有負(fù)號(hào)指示的則很可能對(duì)應(yīng)的那相電流的進(jìn)出線反了。</p><div
