Biometric Scanner Based Circuit Breaker on Transmission Line

Electric linemen currently have to ask staff members to turn off the lines that need maintenance or repairs. There is a significant possibility of misunderstandings and a possible danger to life. The goal of the suggested solution is to solve this issue by offering a safe way to turn the supply on and off in line. This system uses a fingerprint sensor for authentication because it shouldn’t be accessible to everyone. We have a backup system with user authentication in place in case the fingerprint detection fails or encounters issues. The electric lineman uses a fingerprint sensor to submit a request for system access. Access is allowed and the line can be turned on or off based on need if the fingerprint matches the one on file. The output status of an allowed or denied access is displayed on the LCD. Relays are used to connect or disconnect loads and signal whether a load is on or off based on the system’s condition. The microcontroller, which oversees all system operations, must be configured to produce results upon request from authorized users. The suggested method seeks to safeguard electric linemen’s safety and lessen the possibility of human mistake.
