Xbee Transformer/Generator Health Monitor Project

Download Document/Synopsis
Our proposed project aims at remotely getting the information on distribution transformers using a GSM modem or Xbee. This application requires a temperature sensor, three potential transformers along with three current transformers. They work together to monitor three parameters of a generator/transformer and send this data to remote location.
Three analog values are obtained through multiplexing in connection to a programmable 8051 family MC. It is connected through an ADC 0808 IC. All of the monitored sensor values are then sent in a sequential order according to the multiplexing frequency obtained from ADC by the microcontroller. It sends these parameters to the XBEE module that operates at 2.GHz in order to send over the data.
A microcontroller interfaced system is used as a receiver that is used to receive the real time data along with error signals transmitted for desired relay required for displaying output on an LCD display.
A step down transformer (230/12V) that is used to step down the transformer voltage to 12V is used with power supply. A bridge rectifier is then used in order to convert it to DC. A 7805 voltage regulator is then used to regulate it to +5 V that is required for the MC operation.
