There are also many problems in the power supply,such as the inability of the backup power supply to be switched on by itself,the unreasonable configuration of the insurance and the internal failure of the power supply causing the power supply to be interrupted,the fluctuation of the temperature and voltage power supply caused by the malfunction of the protection and the poor contact of the plug,resulting in no output of the temperature and pressure power supply;some The entire cabinet of the system supplies all input signals or a power supply with a large external load through one fuse,and the remaining control power supply is neither connected nor redundant.

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。
