Tata Power Delhi Distribution Ltd (Tata Power-DDL) has been granted a 20-year patent for its innovative self-regenerating transformer breather, designed to protect transformers from moisture damage and extend their lifespan.

This newly patented device is aimed at reducing moisture ingress into transformers, which can cause outages and decrease their longevity. By utilizing waste heat from the transformer’s top plate, the breather minimizes moisture content in the air entering the transformer, enhancing its efficiency and durability.

Unlike traditional designs, where Silica gel in the breather must be replaced frequently, Tata Power-DDL’s self-regenerating technology requires gel replacement only during routine maintenance, typically every two years. Conventional breathers, on the other hand, need 4-6 replacements within the same time frame.

Developed by Tata Power-DDL’s engineering team and successfully tested in 2015, the technology was first piloted in 2016-17 with impressive results. This advancement significantly reduces maintenance demands, improving operational efficiency for power utilities.

Gajanan S Kale, CEO of the company, highlighted the breakthrough, stating, “This patent reinforces our technological leadership, ensuring our infrastructure is resilient to challenging weather conditions.” Tata Power Delhi Distribution Ltd (Tata Power-DDL) is a joint venture between the companyand the Government of NCT of Delhi, responsible for the power distribution in the northern and north-western parts of Delhi.
