If you missed our April 10th Power Panel, now’s your chance to catch up! Industry leaders came together to explore the critical role of On-Load Tap Changers (OLTCs) in maintaining voltage stability and grid reliability.

On-load tap changers (OLTCs) are often the unsung heroes of power systems, quietly ensuring voltage stability and supporting the continuous flow of electricity. As the pressure on global power grids intensifies, the importance of effective OLTC monitoring, diagnostics, and maintenance has never been more critical. A failure in this key component can have far-reaching consequences, which is why staying ahead with the latest tools, strategies, and technologies is paramount to grid reliability and transformer longevity.

Our panel features:

• Robert Vary, President & CEO of Reinhausen Manufacturing Inc.

• Shane Oakley, Regional Director at NASS, Voltyx

• Lance Lewand, R&D and Technical Director, Doble

Moderated by:

• Alan Ross, Managing Editor at Transformer Technology

Key Takeaways from Power Panel:

• Rising grid demand is driven by AI data centers and renewable energy.

• Supply chain issues are delaying delivery of OLTCs and transformers.

• Aging workforce threatens institutional knowledge in power systems.

• Predictive diagnostics (e.g., DGA, vibro-acoustics) are essential for early fault detection.

• Vacuum OLTCs offer longer life and lower maintenance vs. oil-based versions.

• Retrofit solutions allow OLTC upgrades without full transformer replacement.

• Digital twins and real-time monitoring systems (like ETOS) improve decision-making. 

Did you know? Digital twins of transformers can integrate data from OLTCs, bushings, cooling systems, and DGA — allowing utilities to predict failures before they happen and extend asset life.

From digital monitoring to predictive strategies, this session provides actionable insights to help you optimize OLTCs and strengthen grid performance – watch the session on demand and stay ahead in the evolving energy landscape!
