Nowadays, the current power system deals with huge power network as well as associated electrical equipment. During the electrical fault or short circuit, the power network will suffer from a high stress of fault current in them which may harm the equipment permanently. For conserving the power networks and equipment, the fault current should be very cleared from the system as fast as possible. To overcome this problem, the proposed system password based circuit breaker gives a solution to ensure lineman security. In this project, the control (ON/OFF) of the electrical lines lies with lineman. This project is set in such a way that preservation staff or lineman has to enter the password to ON/OFF the electrical line.
Now, if there is any mistake in the electrical line, then the lineman will control the power supply to the line by pressing the password and happily repair the electrical line, and after coming to the substation lineman switch on the supply to the particular line by pressing the password. Separate passwords are allocated for every electrical line.
