Our History
Decades of Grid Protection Excellence: A Brief Intro to Qualitrol’s Legacy and Milestones.
Qualitrol was founded in 1945 by George Ford in Fairport, New York, with a clear purpose: to manufacture pressure relief devices for the electrical industry. From the beginning, the company earned a reputation for quality and dependability—values that remain central to our identity today. In 1986, Qualitrol joined Danaher Corporation’s Instrumentation Unit, gaining access to expanded resources and global distribution channels. This pivotal moment accelerated our growth and broadened our reach across the energy sector.
Over the decades, Qualitrol has strategically acquired companies that complement and strengthen our mission. These acquisitions have brought specialized expertise in transformer instrumentation, fault recording, partial discharge monitoring, fiber optic sensing, and dissolved gas analysis. Each brand has enriched our portfolio, enabling us to deliver comprehensive condition monitoring solutions that support safe, efficient, and uninterrupted power delivery across the globe. Today, our legacy is built on decades of innovation, customer trust, and a relentless commitment to powering a more reliable future.
As the energy landscape has transformed, so has Qualitrol. We've consistently adapted to meet the changing needs of the grid—developing smarter, faster, and more predictive technologies that empower utilities to act before failures occur. Our legacy is one of forward-thinking innovation, where every product and service is designed to enhance asset performance, reduce downtime, and support a more resilient power network. We don’t just respond to change—we lead it.
Progress is part of our DNA. From launching industry-first technologies to expanding our global footprint, Qualitrol continues to evolve—internally and externally. Our journey includes the integration of world-class brands, the development of advanced service offerings like Xpert Services and our Center of Excellence, and ongoing improvements to our digital presence and customer experience. Every milestone reflects our dedication to continuous improvement and our unwavering focus on delivering solutions that support the world’s energy infrastructure.
Qualitrol’s history is built on a foundation of innovation, safety, and progress. Over the decades, our products and services have set new standards for transformer monitoring—helping utilities around the world protect their assets and improve grid reliability. Along the way, we’ve grown through the strategic acquisition of specialized brands, expanding our capabilities and deepening our expertise. Today, that legacy continues as we develop smarter, more connected solutions that empower our customers to monitor the health of the power grid with greater confidence than ever before.
