Abstract: A Remote Monitoring System plays an important role in many applications. This paper proposes an innovative design about the development of remote monitoring system for a three-phase 10-kVA Switchable Distribution transformer with the help of a PIC microcontroller and Zigbee-based Wireless device. The PIC microcontroller from microchip helps in controlling the switching devices and monitoring the current, voltage and temperature of the transformer. The Zigbee-based wireless device is used as long range wireless communication between the modules. The information is transmitted point by point using Zigbee transmitter and receiver and is sent to the server module to check the state of the transformer. It has a data rate speed of 250 Kbps with minimum power consumption and has a transmission distances range from 10 to 100m. The data transmission rate is higher than other wireless systems. This is user friendly and can be achieved at low cost. This handles the transfer of parameters such as voltage, current and temperature as digital data from current transducers, voltage transformers and from temperature sensors to the server module through wireless communication. This system helps in reading sensor, controlling switches, monitoring and data protection.
