Powering Reliability Without Outage (2008)
Throwback to one more of our early and inspiring milestones!
In 2008, at the 220kV Substation, a 100MVA transformer at PSEB Rajpura (Punjab) underwent online maintenance using our Online Transformer Dryout System and Online OLTC Filtration System all executed without any outage.
This successful result not only reaffirmed the faith of our client but also gave us a strong push to further enhance the ruggedness and field reliability of our systems.
At PTss, delivering high-impact, no-outage solutions for transformer health has always been our mission — and this case from 2008 stands as a strong example of that commitment.
