The Objective Of This Project Is To Monitor The Transformer Parameters Such As Voltage, Current, Frequency And Temperature And To Control Using Microcontroller With The Help Of Zigbee Transceiver. This Project Prescribe About The Transformer Which Is Used For Powering The Machines Where The Incoming Supply Voltage And The Rated Voltage Of The Distribution System Are Different. The Transformer Windings And Insulation May Get Damaged Due To Severe Fault Conditions .In Many Cases The Transformer May Burst. It Explain How To Monitor The Above Parameters And Isolate The Power Supply During Emergencies. The Output Voltage Is Measured With The Help Of Potential Transformer. The Output Current Is Measured With The Help Of Current Transformer, Similarly Temperature Sensor Is Used To Monitor Temperature Rise In The Transformer. Zigbee Is Wireless Transceiver Where We Can Send And Receive The Data Through This Module. The Monitored Parameters Will Be Sent To The PC Through Zigbee. The Cooling System Of The Transformer Is Performed If Winding Temperature Exceeds A Certain Value. During Severe Fault Conditions, Relay Is Operated And The Power Supply To The Transformer Is Isolated.
