MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631031265 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on March 16, for 'over-voltage and under-voltage protection system using arduino.'
Inventor(s) include Kamalika Banerjee; Sarbani Ganguly; Bansari Deb Majumder; Maitrayee Chakrabarty; Sonu Kumar Tiwari; Prabhat Kumar Singh; Zaid Ahmed; and Md. Khalid Miraj.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides an automated protection system for electrical loads against over-voltage and under-voltage conditions. The system comprises a voltage sensor for real-time monitoring of supply voltage, an Arduino microcontroller for processing sensor data, and a relay module for load isolation. The microcontroller executes software-defined logic to compare incoming voltage levels against programmable thresholds. If a voltage anomaly is detected, the microcontroller triggers the relay to disconnect the load, thereby preventing electrical damage. The system features an automatic reconnection mechanism that restores power once the voltage stabilizes within safe limits. This low-cost, programmable solution is adaptable to various voltage standards and provides a reliable alternative to traditional hardware-only protection relays."
