Abstract:
Electrical power isolation is a crucial safety measure in industrial and commercial environments
to prevent unauthorized access and ensure maintenance personnel's safety. This project focused on
the Design of a Two-Factor Authentication Electric Power Isolation System. The system utilized
an Arduino Nano microcontroller to process user input via a keypad, controlling an MG99R servo
motor to engage or disengage the isolator switch. Additionally, a GSM module was incorporated
to send SMS notifications upon successful or failed authentication attempts, ensuring real-time
alerts to authorized personnel.
To enhance system reliability, the design included audio-visual indicators, such as an alert buzzer
for incorrect password attempts and an LED indicator to display system status. The system was
first simulated in Proteus software before hardware implementation to validate its functionality
and effectiveness. This project is applicable in industrial switchgear, power distribution systems,
and maintenance environments, where controlled access to electrical isolation is critical for safety
and operational efficiency.
The developed system offers an automated, secure, and efficient solution for power isolation,
reducing the risks associated with unauthorized access and accidental power restoration. Future
enhancements may include biometric authentication, IoT integration, and remote-control features
for improved accessibility and security.
