PROJECT DESCRIPTION

This project is proposed to acquire the parameters of a distribution transformer, such as current, voltage and temperature using sensing devices like temperature sensor, voltage and current transformers to send those values to remote area using GSM communication.

The proposed system consists of two blocks: transmitter and receiver block; both use a microcontroller of 8051 family and a rectified power supply. This project consists of a GSM modem for communication.

A GSM modem interfaces to the microcontroller through a level shifter at transmitting end and receiving end.  8 sensors are interfaced to the microcontroller at the transmitter end through analog to digital converter (ADC) for monitoring the parameters of the transformer. The loads are controlled by  relays interfaced to the microcontroller at the receiver end through  relay driver. The LCD is interfaced to the microcontroller for displaying the information.

Three sensors are fixed at the transmitter end with a certain range of each parameter; and, if these parameters exceed the fixed limits, then the transmitter sends a signal to the receiver end using the GSM modem connected to the microcontroller to switch a load as warning using relay, and displays the message on the LCD display.
