Development of automatic line tracking inspection device for high voltage transmission lines using ground control

Abstract

Due to power fluctuation people suffer a lot as the electrical items get

damaged easily. Inorder to avoid such problem we planned to developed this

system. Aim of project is to develop an Automatic ground control system for the

Home and Industrial Appliances using PIC Microcontroller. Here the 230 volt bulb

is used for loads which are commonly used in every home.

When the voltage fluctuation occurs in the power line then the loads

connected will be automatically grounded and after some times when it resumes

the normal conditions it should ON. Automatic ON/OFF Switching system is

performed by the microcontroller. Voltage will be displayed in the LCD during

normal and short circuit period.
