A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. It plays a vital role in power generation and in different sections such as generation unit, substation unit and distribution unit based on its needs and requirements. We control and monitor 3 parameters that are voltage, current and temperature. Monitoring and control is performed by the LM35 temperature sensor, the microcontroller and the RF module. Therefore, it is necessary to continue to check the condition when the temperature, pressure and environmental conditions increase. It is detected by the sensor and is the input signal to the microcontroller. The signals are monitored and controlled through the RF module. The system is the design to detect the characteristics of the transformer and send the information to the controller, then the controller will do the transmission through RF to the client. Remote receiver, which is also a microcontroller unit. Does the comparison between the stored value and the ref value. If a fault or error is detected, it is displayed on the LCD.
