The SOE record is the sequence of events record.When the power equipment undergoes a remote signal displacement such as a switch displacement,the power protection device or smart power meter will automatically record the displacement time,the reason for the displacement,and the corresponding remote measurement value when the switch trips(such as Corresponding three-phase current,active power,etc.)to form SOE records for later analysis.Many relay protection equipment and smart power meters,such as power protection meters from GE Power,Schneider Electric,ABB,Siemens and other manufacturers,special power RTU equipment,etc.have SOE recording function.
SOE记录即事件顺序记录，当电力设备发生遥信变位如开关变位时，电力保护设备或智能电力仪表会自动记录下变位时间、变位原因、开关跳闸时相应的遥测量值（如相应的三相电流、有功功率等），形成SOE记录，以便于事后分析。许多继电保护设备以及智能电力仪表，如GE电力、施奈德电气、ABB、西门子等厂家的电力保护仪表、专用电力RTU设备等等均有SOE记录功能。
