Our Approach

For nearly 40 years, SEL has specialized in designing, manufacturing, and implementing solutions for power system challenges. In the event of an electrical fault or unexpected outage, our fast-tripping digital relays and sophisticated automation systems respond quickly to isolate problematic portions of your power system and automatically balance load and demand using alternative power sources.

Scalable Designs

The Uptime Institute categorizes data centers into four tiers based on their ability to handle planned and unplanned service disruptions. These tiers cover a broad spectrum of facilities, ranging from data centers with annual downtime in the dozens of hours to hyperscalers that never go offline.

We design our solutions to scale effectively at every stage of that spectrum, allowing you to deploy new facilities rapidly with highly configurable, switchgear-agnostic protection and control solutions. At the enterprise level, these solutions streamline electrical power management system (EPMS) integration and enable centralization for large-scale designs.

Our Solutions

Every solution from SEL delivers field-proven reliability by starting with the fundamentals of protection. Our products are designed to protect critical power system equipment against failure or damage—tripping for faults when they’re supposed to and, just as importantly, not tripping when they shouldn’t.

Beyond the fundamentals of protection, tailor solutions to your operational needs with automated failover to adjacent sites, extensive analytics and reporting, and strict OT cybersecurity.

Critical Protection

Power system protection has always been the core of SEL’s mission. Our comprehensive catalog of solutions helps ensure uninterrupted power to servers and cooling systems.

Protect utility interconnections using IEEE C37.118 synchrophasors and enhanced circuit breaker monitoring.
Take advantage of features such as an intuitive touchscreen, adaptable I/O options, and detailed event analysis for feeder protection.
Integrate overcurrent protection, Time-Domain Link (TiDL) technology, and dynamic zone configuration into your bus protection.
Guarantee motor operation using differential protection, broken rotor bar detection, and comprehensive asset monitoring.
Safeguard transformers with multiwinding protection, frequency tracking, and through-fault monitoring and protection.
Protect and control generators using current differential protection, islanding detection, and breaker wear monitoring.
Add arc-flash protection to reduce incident energy by up to 88%, helping keep operations and maintenance personnel safe and limit equipment damage—even during a catastrophic event.

Power Quality Monitoring

Our power quality and usage monitoring devices are fully Class A-compliant to the IEC 61000-4-30 power quality standard. They also exceed ANSI C12.20-2015 0.1 and IEC 62053-22:2003 0.1 S accuracy class requirements, enabling operators to identify power system anomalies and isolate their source with confidence.

With reliable Class A measurement, colocation facilities can simplify client billing and management.

Our Services

From consulting and design to installation and commissioning, SEL is a full-service partner with the added expertise and connections that come with manufacturing the products we install.

Our teams of experienced engineers are prepared to assist you by standardizing protection scheme designs, performing system modeling and studies, and testing your system for cybersecurity preparedness.

Design Standardization and Implementation

Our teams work with you to standardize protection scheme designs across dozens of facilities, expediting development and construction for new data centers and streamlining upgrades for existing facilities.

System Modeling and Studies

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 power system through the devices that protect and control it.

With the actual protection and control hardware that will be installed in your system wired into our Real-Time Digital Simulator (RTDS) test bed, we use our extensive library of validated power system models to systematically test thousands of faults and adverse scenarios, providing the equivalent of years of operational history in only a few days.

Engineering Services—Cybersecurity

Our cybersecurity professionals provide secure solutions tailored to your priorities and objectives.

Our Support

We believe you should never have to worry about whether your protection and control systems will be working when you need them most. That’s why every device we manufacture comes with a 10-year warranty and free technical support.

It’s been this way at SEL since the company was founded nearly 40 years ago—a major reason why we’re North America’s most trusted provider of protective relays and ranked #1 by international utilities in price, service, and support.

The Industry’s Best Warranty

SEL devices are designed for a working life of at least 20 years, and every SEL-manufactured device comes with a 10-year warranty—the best in the electric power industry. If it fails under warranty, repair and replacement are free.

We always do all that we can to repair any returned product, whether it meets our warranty or not.

Proven Reliability

SEL products are designed and manufactured for the world’s most challenging environments, exceeding all industry standards for temperature, shock, and electric stress. An optional conformal coating for circuit boards adds an extra level of protection against contaminants in extreme environments.

Our products have a mean time between returns for repair (MTBR) of more than 250 years, based on observed field performance. This means that if you have 250 SEL products installed in your systems, you can expect to have less than one unscheduled removal from service per year for any reason, whether it’s a defect or an external factor such as overvoltage, overcurrent, wildlife damage, or environmental exposure.
