Protection, robustness, maintainability and cybersecurity — these are four key factors to successfully modernizing your substation with a digital secondary system (DSS). On October 7, 2020, SEL engineers will present a webinar to discuss how these factors apply to SEL Time-Domain Link (TiDL) technology, one of SEL’s DSS solutions.
SEL encourages employee and community to remain diligent in the fight against COVID-19.
In power system protection, every millisecond counts. Faster fault clearing improves public and utility personnel safety, widens transient stability margins, limits equipment wear, improves power quality and confines property damage. Schweitzer Engineering Laboratories has released the SEL-T401L Ultra-High-Speed Line Relay, which combines the field-proven traveling-wave-based and incremental-quantity-based technologies pioneered in the SEL-T400L Time-Domain Line Protection with a complete suite of phasor-based protection functions that you expect in a line protection system.
For utilities looking for ways to mitigate wildfire risk due to downed conductors, SEL can help. High-impedance fault (HIF) detection is a key technology for detecting downed conductors, a critical component of a complete wildfire risk mitigation program.
For utilities faced with converging information technology (IT) and operational technology (OT) networks, there are many challenges to consider. These challenges include performance for protection applications, security, demarcation of responsibilities and more. On August 26, 2020, SEL engineers will present a webinar that describes how SEL ICON virtual synchronous networking (VSN) helps utilities address convergence challenges.
Schweitzer Engineering Laboratories has released Flow Auditor, the first application in the new SEL-5057 SDN Application Suite. Flow Auditor streamlines data collection for NERC CIP compliance reporting.
Advanced protection, monitoring and communications are critical when it comes to safeguarding the substantial investments made in generating facilities. The new SEL-400G Advanced Generator Protection System offers primary and backup protection for generators of all sizes and types, including hydro, pumped-storage hydro, steam turbine and combustion gas turbine generators.
When Enel-Codensa—one of Colombia’s leading electric utilities—encountered a major obstacle to upgrading their hydroelectric facility’s busbar protection scheme, they decided to partner with SEL to find a solution. SEL’s proposal featured Time-Domain Link (TiDL) technology, which would not only solve Enel-Codensa’s problem but also improve the safety, security, and efficiency of their substation.
Power system complexity continues to increase as nonlinear devices, such as variable-frequency drives, power supplies, and inverters, are added. However, increased visibility of the real-time power system status while in the field can make work simpler for operators, technicians, and engineers alike. The SEL-735 Power Quality and Revenue Meter will soon be available with a color touchscreen display, improving real-time system visibility.
Advanced protection, monitoring and communications are a critical part of protecting the substantial investments made in generating facilities. These capabilities allow facility operators to detect faults earlier, limit generator damage and return to service faster.
A new SEL white paper provides insights into capacitor bank management and control. It describes the function of capacitor banks in the distribution system and identifies common methods for controlling capacitor banks, including their benefits and challenges.
The Tohono O’odham Utility Authority (TOUA) is a small utility nestled in the heart of the Sonoran Desert in the Southwest U.S. They were one of the first to add the SEL-T400L Time-Domain Line Protection to their transmission line system with contacts ready to trip.
Schweitzer Engineering Laboratories has released the SEL-734W Capacitor Bank Control and SEL-8340 Wireless Current Sensor solution, offering utilities a safer, simpler, and more cost-effective way to improve distribution power quality and efficiency.
Dr. Ed Schweitzer's letter to the community.
New enhancements for the SEL-751, SEL-710-5, SEL-700G, and SEL-787-2/-3/-4 protective relays are now available. These enhancements save power system operators time by simplifying testing, allowing remote access, and offering additional onscreen controls.
