Tata Power-DDL secures patent for transformer moisture protection device

Tata Power Delhi Distribution Limited (Tata Power-DDL) has been granted a 20-year patent for its innovative 'Self-Regenerating Transformer Breather,' designed to protect electric transformers from moisture and prolong their operational lifespan. This breakthrough is part of the company's broader efforts to enhance efficiency and reduce maintenance costs in electricity distribution.

The new technology significantly cuts down the need for frequent silica gel replacements, which are commonly used to shield transformers from moisture. Traditionally, silica gel needs replacement four to six times over a two-year maintenance cycle. However, with the self-regenerating breather, this requirement drops to just once every two years, aligning with the regular transformer maintenance schedule.

The self-regenerating breather utilises waste heat from the transformer's top plate to reduce moisture in the air inlet, allowing the silica gel to regenerate. This not only reduces maintenance frequency but also extends the gel's lifespan by up to three years in outdoor conditions.

Developed by Tata Power-DDL's engineering team, the device was first tested in December 2015, with a pilot installation of 20 breathers in 2016-17. The success of these trials led to the patent filing in 2016.

Gajanan S. Kale, Chief Executive Officer, Tata Power-DDL, stated, “At Tata Power-DDL, we continually innovate to tackle operational challenges. This patent showcases our technological expertise, ensuring a resilient infrastructure capable of handling extreme weather conditions while maintaining uninterrupted power supply.”
