Multilayer Lineman Life Protection Using OTP

This research article presents a comprehensive multilayer security system for protecting electrical linemen during maintenance and repair operations on power transmission and distribution lines. The proposed system integrates One- Time Password (OTP) authentication as a critical safety mechanism to prevent accidental energization of lines while workers are present. Traditional safety protocols rely heavily on manual lockout-tagout procedures and communication systems that are prone to human error, leading to numerous fatalities and injuries annually. The multilayer approach combines OTP-based authentication, real-time location tracking, biometric verification, and automated circuit isolation to create redundant safety barriers. This paper examines the technical architecture, implementation challenges, and validation results of the proposed system through simulation and field trials.
