Homegrown Robot Promises to Cut Eskom Power Line Faults
A South African-built robot that travels along live power lines is helping Eskom detect potential faults before they escalate into blackouts, according to Cape Town Etc. The Powerline Inspection Robot originated as a master’s project at the University of KwaZulu-Natal and was later commercialised through the university’s InQubate programme.
Supported by Eskom and the KwaZulu-Natal Government through research and technology funding, the project has grown from an academic prototype into a patented product protected both in South Africa and the United States. This international patent coverage paves the way for broader deployment of the technology.
The robot traverses live conductors on small wheels and uses a combination of visible-light cameras, infrared and ultraviolet imaging, and machine vision systems to inspect hardware on the lines. It can navigate past towers, operate under strong winds and heavy rain, and geo-tag images to help engineers monitor the condition of power infrastructure over time.
“Our research and development is conducted by the Eskom Research, Testing and Development (RT&D) – investing largely in examining emerging technologies and innovation to ensure Eskom remains both competitive and sustainable.”
Innovation for Reliability
This homegrown innovation demonstrates how South African engineering is contributing to greater grid reliability and technological progress in utility management.
Author’s summary: A South African robot developed through university research now assists Eskom in inspecting live power lines safely, reducing failures and modernising maintenance practices.
