西門子SIPROTEC 4系列保護(hù)具有友好的人機(jī)界面,7UT6系列的變壓器差動保護(hù)包含了縱聯(lián)差動保護(hù)、低阻抗或高阻抗原理的零序差動保護(hù)以及復(fù)壓過流、零序過流等后備保護(hù)功能，可快速而有選擇性地切除發(fā)生在各種變壓器上的內(nèi)部故障，同時(shí)也可為發(fā)電機(jī)、電動機(jī)、單母線和短引線等提供差動主保護(hù)。內(nèi)置的12組用戶自定義保護(hù)功能，可根據(jù)現(xiàn)場特定需求創(chuàng)建各類電流、電壓以及功率保護(hù)等。
7UT6還提供控制與自動化功能：部分型號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)開關(guān)或刀閘的分合操作。通過內(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)的多種開放、標(biāo)準(zhǔn)的國際通訊規(guī)約，設(shè)備
可方便地接入各種自動化系統(tǒng)。
差動保護(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折線差動特性曲線附加制動區(qū)抗CT飽和差動特性曲線可整定為自動抬高零差保護(hù)簡單、可靠，靈敏度與變壓器帶載特性無關(guān)最小靈敏電流定值達(dá)3mA
