7UT6還提供控制與自動(dòng)化功能：部分型號(hào)的大屏幕液晶窗可實(shí)時(shí)顯示回路和設(shè)備狀態(tài)，配合就地控制鍵可方便地實(shí)現(xiàn)開(kāi)關(guān)或刀閘的分合操作。通過(guò)內(nèi)置
的CFC可編程邏輯功能，用戶能非常靈活地實(shí)現(xiàn)如開(kāi)關(guān)聯(lián)閉鎖、參數(shù)越限告警等功能。支持包括IEC61850在內(nèi)的多種開(kāi)放、標(biāo)準(zhǔn)的國(guó)際通訊規(guī)約，設(shè)備
可方便地接入各種自動(dòng)化系統(tǒng)。
差動(dòng)保護(hù)零序電流處理：
-零序消除：傳統(tǒng)的零序分量濾除方法-零序補(bǔ)償：差入中性點(diǎn)零序電流，保持100%的區(qū)內(nèi)接地靈敏度，且僅在故障相反應(yīng)出差流4折線差動(dòng)特性曲線附加制動(dòng)區(qū)抗CT飽和差動(dòng)特性曲線可整定為自動(dòng)抬高零差保護(hù)簡(jiǎn)單、可靠，靈敏度與變壓器帶載特性無(wú)關(guān)最小靈敏電流定值達(dá)3mA
