Our Approach
At SEL, we work to ensure that everyone has access to safe, reliable electric power. This is why, from our company’s founding to now being a global leader in electric power engineering, we have always treated our customers as partners.Whatever the scale of the project may be—from a single device to system-wide modernization programs—we make sure designs are firmly rooted in the first principles of engineering and then develop a solution that fits your needs.After your modernized systems are in service, SEL project and application engineers provide thorough training. We ensure that partners using our products, solutions, and services receive comprehensive support for the entire project life cycle.
When you partner with SEL, you have access to our experts before and after project completion.SEL ES supports every phase of your project, from protection studies and system modeling to design, procurement, installation, and commissioning.We use advanced modeling and simulation, informed by decades of power engineering experience, to analyze system requirements, validate full system designs, and optimize the performance of the grid.After your system is commissioned, we're ready to help if you have questions or require service. We support every device we manufacture and every system we design for the entirety of its life cycle.
When you undertake a project with SEL ES, you benefit from our commitment to securing and streamlining the supply chain, whether it's a component, circuit board, device, or panel. We manufacture an increasing number of components, providing greater control over the cost, lead time, and quality of our products.We ensure the quality of our material and service suppliers through careful evaluation, including audits of their facilities and processes, and continuous testing of the integrity of their deliverables. We take a comprehensive five-part approach to this evaluation, which also includes building strong relationships with our suppliers. If we find performance variations in our products or services, we investigate the root cause of the problem, confirm we have properly identified it, and eliminate it.
