NEW DELHI — Advancing its digital transformation footprint in heavy industrial safety, NTPC Limited has been awarded a formal patent by the Government of India for an indigenous technology titled “A Method and a System for Accessing Electrical Breaker Modules.”
The patent, officially registered under Patent No. 592308 on June 15, 2026, introduces an automated, data-driven framework designed to safeguard engineers operating high-voltage switchgear installations.
Key System Architecture and Capabilities
The patented invention replaces conventional, error-prone manual lockout procedures with an integrated, intelligent access network:
-
Enterprise-Level Syncing: The smart access system connects directly with the utility’s SAP enterprise software and live Permit-to-Work (PTW) systems, verifying that physical field actions align precisely with digital maintenance clearances.
-
Digital Interlocking: Utilizing multi-factor authentication, the technology restricts physical access to breaker modules. It ensures that only certified technicians with active, validated work orders can open or modify high-voltage panels.
-
Erasing Critical Blind Spots: By enforcing rigid protection interlocks, the system neutralizes risks associated with operational multiplicity and duplicity. This safeguards against the catastrophic error of a technician inadvertently isolating or working on the wrong electrical equipment.
The Engineering Brains Behind the Patent
The safety solution was designed and developed by an in-house team of NTPC technical experts spanning multiple generation facilities:
-
Shri Sandeep Kumar — DGM, Corporate Centre (Solar)
-
Shri Gnyanankur Sonowal — DGM, Electrical Maintenance Department (EMD), NTPC Bongaigaon
-
Shri Ashutosh Kumar — Senior Manager (Operation), NTPC Farakka
Enhancing Workplace Safety Standards
The milestone highlights NTPC’s focus on using digital innovation to achieve zero-accident operations across its pan-India power generation footprint:
The Industrial Viewpoint: As India’s largest integrated power utility, securing this patent demonstrates NTPC’s capability to build proprietary, high-tech industrial solutions. By blending data-driven gatekeeping with physical equipment handling, the invention significantly tightens workplace compliance, cuts down human error, and ensures greater operational reliability for critical energy infrastructure.
