Design of Remote Terminal Unit (RTU) Panel Supply Monitoring Based on IOT Case Study at PLN

PLN(electricity supply company in Indonesia) uses the Supervisory Control and Data Acquisition (SCADA) system which consists of RTU(Remote Terminal Unit) panels for remote control. Many RTU panels failed to connect to PLN SCADA's system. One reason is the decrease in the supply voltage of the RTU panel. PLN carries out maintenance to handle that. To increase the productivity of maintaining the problem by PLN, We made a prototype monitor RTU panel supply in mobile and real-time based on internet of thing(IoT). The device performs data acquisition of Alternating Current(AC) voltage supply, Direct Current(DC) voltage supply in adapter and battery, test the condition of the RTU panel supply battery with the android application as GUI (Graphic User Interface). The android application can also show RTU panel locations and routes. With this prototype, it is expected to increase efficiency, productivity and shorter maintenance time on RTU panel maintenance so that SCADA is always ready to be used in the distribution network at all times.
