SEL manufactures high-quality cables for connecting a variety of devices. You can order cables to specific lengths to meet your needs. Each cable is quality tested to ensure reliability and proper operation.
This webinar introduces new benefits that SEL-5702 Synchrowave Operations Software offers to users, including preventing incipient PT failures and quickly locating generation loss events.
This webinar introduces and demonstrates SEL’s next-generation solution for automating fault location, isolation, and service restoration (FLISR)—available in the new Distribution Management System (DMS) application suite on the SEL Blueframe software…
This recorded webinar highlights two solutions for monitoring harmonic distortion and confirming IEEE 519 compliance: SEL-5705 Synchrowave Reports, a new browser-based meter reporting tool, and the SEL Real-Time Automation Controller (RTAC).
This white paper provides both theoretical and real-world examples with questions that can be used to gain experience with symmetrical components. The full solutions to these questions can be found in the white paper "Tutorial on Symmetrical Components, Part 2: Solutions."
Event reports continue to be an invaluable feature in microprocessor-based relays. Some events are relatively straightforward to analyze, and others require experience and considerable knowledge of the power system and protective relay system in order to find root cause. This session provides several advanced real-world event examples, time to evaluate them, and solutions.
Event reports have been an invaluable feature in microprocessor-based relays since the initial introduction of the technology. The days of unknown root cause for an operation, lengthy outages, or unexplained test results are largely over due to this tool and the ability of engineers and technicians to use it. We must practice to become proficient at analyzing event reports. This session provides real-world event examples, time to evaluate them, and solutions.
This white paper provides both theoretical and real-world examples with questions and solutions that can be used to gain experience with symmetrical components.
This paper describes how SEL software-defined networking (SDN) can significantly reduce the time and effort required to collect data and provide evidence for CIP-007-6 R1.1 and CIP-010-2 R1.1.4 compliance. It also describes how SEL SDN can assist with meeting NERC CIP-005-5 R1.1–3 requirements [3].
This document defines AutoRANGER® trip logic, inrush restraint (IR), installation considerations, fault indication modes, principles of operation, battery conservation, and test/reset methods.
As part of our overall mission to make electric power safer, more reliable, and more economical, SEL develops and provides innovative, simple to use, robust technologies to protect, automate, control, monitor, and analyze power systems. An essential element of this strategy is the development of appropriate communications technologies and protocols.
This white paper describes how to use the SEL Real-Time Automation Controller (RTAC) to build an automated system to continuously monitor and validate many of the components identified in the NERC PRC-005 standard.
