Model:S253(For Transformer) Name: 3-Phase Electric Measuring Transformer Monitoring and Alarm Remotely The Cellular(GSM/GPRS/3G/4G/NB-IoT) 3-Phase Electric Measuring RTU is special designed for remote monitoring transformer, and measuring the 3-phase 3-wire, 3-phase 4-wire distribution power voltage, current, factor, watts, frequency, active power, reactive power, when overload or loss phase or exceed the pre-set value, then it will alert by SMS, Voice call, Cloud, APP, Wechat, Web Server, SCADA, HMI, DSC immediately. The Cellular 3-Phase Electric Measuring RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, integrated special measurement chip and inbuilt industrial Cellular module. It provides 4 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity. The Cellular 3-Phase Electric Measuring RTU also can be used for monitoring the safety and security of the transformer, e.g. overload, phase loss, oil temperature, oil level, burglarproof, fall down etc. The Cellular 3-Phase Electric Measuring RTU can monitoring and operates the I/O ports by SMS, APP, Web Server, internet, timers and programmed inter-lock events automatically.
