A low cost automation solutions based on recent IOT technology and GSM using embedded processors like ARDUINO UNO for automation of a small substation. This gives the advantage of cost reduction plus a plethora of connectivity options. In this paper, arduino IDE software is used to control a feeder with help of GSM module. Analog and digital parameters from field are monitored and controlled using analog pins, interfacing relays and communication ports available in arduino Uno controller. The automation sequences for control monitoring and protection of the system is defined using c program in such a way that it sends the input parameters in the field side to the registered mobile number. The controls of relays and buzzers are based on the control signals that are sent from the operators. If the current exceeds their limits, the microcontroller will automatically trips the circuit breakers and sends that information to the user through IOT uses esp8266 module.
