Innovation Rooted in Trust, Proven Through Results

At PTss, our journey has always been guided by a single principle: delivering reliability without compromise. From our first steps in transformer dehydration technology to today’s advanced online systems, every milestone reflects the trust and support of our valued utility partners.

Throwback to 2004

Our very first consultancy project with Punjab State Electricity Board, Ludhiana, marked a turning point – a 16/20 MVA, 66/11 kV ECE Make Power Transformer was showing low insulation resistance and poor PI values.

.

➡️ Objective
Improve the HV-E PI value to 1.5

➡️ Challenge
Remove moisture without heating and without taking the transformer offline

➡️ Solution
Deploy PTss’s Online Transformer Dryout System on both the main tank and OLTC tank, while the transformer remained energized

✅ Outcome

• IR/PI values improved significantly
• Oil clarity and dielectric performance enhanced
• No heating. No shutdown. No compromise.

This early success validated our belief in energized moisture management and laid the foundation for developing hybrid transformer dryout systems for both main and OLTC tanks – now used across major substations in India.

📈 Since then, many more case studies have followed each one strengthening our commitment to customer satisfaction and field-tested engineering excellence.
