Abstract
The motivation for doing this project comes from the fact that the private sector have been selling very costly protection systems to the government sector. For the sake of solution, we have designed protection module, ensuring complete security and cost effectiveness. This module monitors the voltage, current and temperature and trips the circuit under any abnormal condition.
The input to this module has been taken through the CT and PT in the form of reduced replica. LM-35is the temperature sensor which will provide the value of temperature. These analogue values are scaled through RC circuit and fed to the PIC (18 F452) microcontroller where the inbuilt ADC convert them into digital form. These values are then compared with the specified values and the signal is generated accordingly. The values are displayed on the LCD. The key feature of this module is the two way communication with the remote responsible personal through GSM. When the fault occurs, the fault information will be immediately sent to the remote personal. If he wants to restore the system he can send the restoring command via SMS and the system will be restored. This module also sends the information on website after specific period continuously. So, we can access the system record from anywhere through internet.
