Rancang Bangun Prototype Sistem Proteksi Transformator Berbasis SMS di Paluta

Abstract

The electricity network system in Paluta still needs a lot ofimprovement, especially in the transformer protection sector, because this is the part that is often problematic. To solve this problem the authors propose scientific research in the form of a prototype SMS-based Transformer Protection System in Paluta. Tomake this system an Arduino R3 device, 800L SIM, Current Sensor, Relay, Buzzer and 16x2 LCD are needed. Microcontroller which controls all components in accordance with its functions, for example, SIM 800L as a tool that provides information in the form of sms to PLN mobile officers. The sensor as a detector of current usage. Relay as a switch that turns on / off the load. Buzzer as an alarm notification in the field. LCD as a monitor on the equipment to display the status of the device. From the results of research that has been done, the performance of this system there are two variables: the first if the load reaches 90% the system will send a warning SMS to the PLN officer and the second if the load reaches more than 100%, the system will work to protect the transformer and send sms to PLN officer.
