Schweitzer Engineering Laboratories (SEL) stands as a prominent provider of advanced power system solutions, dedicated to enhancing the reliability, safety, and efficiency of electric power grids globally. The company designs, manufactures, and supports a comprehensive portfolio of products essential for modern energy infrastructure. Among its innovative offerings is the SEL-2240 Axion Real-Time Automation Controller (RTAC) Module, a versatile device engineered to function as an all-in-one remote terminal unit (RTU), bay controller, power system monitor, digital fault recorder, and continuous waveform streaming device, capable of handling complex automation and monitoring tasks with significantly increased processing performance.

Complementing its automation capabilities, SEL also produces the SEL-T35 Time-Domain Power Monitor. This state-of-the-art instrument is crucial for capturing every nuance of power system disturbances, including harmonics, distortion, and subsynchronous oscillations (SSO), by streaming high-precision AC and DC voltage and current measurements for wide-area, real-time data analysis, trending, and alarming. Through these technologies, SEL enables utilities and industrial clients to gain deeper insights and proactive control over their electrical networks.

Beyond product development, SEL actively engages in large-scale system modernization projects, collaborating with partners to tackle intricate challenges. An example includes their work with Empresa Propietaria de la Red (EPR) on the SIEPAC transmission system, which traverses rugged and multinational terrains in Central America, demonstrating SEL's expertise in delivering tailored solutions for critical infrastructure. Founded in 1984, Schweitzer Engineering Laboratories has expanded into a global enterprise with over 7,000 employees and operates under a unique 100% employee-ownership model, fostering a commitment to long-term stability, customer satisfaction, and continuous innovation in the power systems industry.
