西门子SIPROTEC 4系列保护具有友好的人机界面,7UT6系列的变压器差动保护包含了纵联差动保护、低阻抗或高阻抗原理的零序差动保护以及复压过流、零序过流等后备保护功能，可快速而有选择性地切除发生在各种变压器上的内部故障，同时也可为发电机、电动机、单母线和短引线等提供差动主保护。内置的12组用户自定义保护功能，可根据现场特定需求创建各类电流、电压以及功率保护等。
7UT6还提供控制与自动化功能：部分型号的大屏幕液晶窗可实时显示回路和设备状态，配合就地控制键可方便地实现开关或刀闸的分合操作。通过内置
的CFC可编程逻辑功能，用户能非常灵活地实现如开关联闭锁、参数越限告警等功能。支持包括IEC61850在内的多种开放、标准的国际通讯规约，设备
可方便地接入各种自动化系统。
差动保护零序电流处理：
-零序消除：传统的零序分量滤除方法-零序补偿：差入中性点零序电流，保持100%的区内接地灵敏度，且仅在故障相反应出差流4折线差动特性曲线附加制动区抗CT饱和差动特性曲线可整定为自动抬高零差保护简单、可靠，灵敏度与变压器带载特性无关最小灵敏电流定值达3mA
