In this webinar discover some of the more surprising, lesser-known, and strange-looking waveforms captured while monitoring high-voltage transmission lines. 

Learn how you can use SEL’s modern digital recloser controls to solve protection challenges that have historically been treated as acceptable anomalies. 

This webinar chronicles Consumers Energy’s experience implementing an innovative solution based on the SEL ICON to migrate to digital leased lines and maintain the performance of protection circuits. The solution runs over a telecom carrier network based on Ciena's Carrier Ethernet technology.

This webinar will focus on securing power systems and electrical substations. Our portfolio of services and solutions makes substation operation systems secure and reliable and helps you achieve NERC CIP compliance. 

In the past, power systems were dominated by linear loads and power generation sources. Today, this simple situation no longer exists and power systems include an increasing number of nonlinear loads and sources.

This webinar focuses on SEL’s 15-plus years of experience providing microgrid solutions. We share the success story of our first microgrid project—a solution in the oil and gas industry in 2002—and how we have expanded our solutions in the utility sector with remedial action schemes and other complex systems.

For years, many utilities have managed two communications networks: one based on time-division multiplexing (TDM) and tuned for the demanding requirements of operational technology (OT) applications and a second for information technology (IT). With the advent of high-bandwidth packet-based technologies, such as Multiprotocol Label Switching (MPLS) and Carrier Ethernet, there is a push to move toward a converged network model to increase the efficiency of assets.

In this webinar, Dr. Bogdan Kasztenny will discuss the challenge of deciding to reclose or not reclose on hybrid transmission lines. A new solution that uses fast and accurate fault locating allows autoreclosing cancel logic to be applied if the fault is on the underground cable portion of the line.

This webinar examines several benefits of implementing distribution network automation using fault location, isolation, and service restoration (FLISR). Distribution automation is examined for permanent faults, open-phase conductors, loss of source, substation events, and more.

This webinar will discuss a new point-to-point digital secondary system solution that was designed with simplicity in mind—Time-Domain Link (TiDL) technology. Learn how a TiDL system works, how easy it is to deploy, and how troubleshooting is simplified.

With many utility IT departments driving their network infrastructure towards packet-based solutions, it has created the challenge of how to engineer Ethernet-based pilot channels to provide the determinism and latency required for protection. This webinar presents a technology approach for guaranteeing deterministic performance over Ethernet-based wide-area networks (WANs).

The amount of data that today's digital relays, recloser controls, and other power system devices collect is astounding. It is a daunting challenge to sift through the data to make sense of the trends, patterns, and behaviors. The key to big data is knowing how to organize it so that it becomes an advantage, rather than a hindrance.

This webinar will examine several common bus configurations, present appropriate protection schemes for each configuration, and analyze the protection scheme complexity, advantages, and disadvantages.

Organize, visualize, and optimize energy usage with data analysis tools. Apply easy-to-use system-level software reports to quickly identify trends and opportunities for improvement, enabling operators to take actions that decrease energy costs.

We will discuss applications of negative-sequence differential protection for lines and transformers, negative-sequence directional elements for turn-to-turn faults in reactors and stators, and protection principles for generator turn-to-turn faults.

The topics discussed will include the following: 1. Load-Shedding Systems 2. Generation-Shedding and Runback Systems 3. Remedial Action Systems

In this webinar, the presenter will review time-domain line protection elements and illustrate their operation performance using real-world faults and digital simulations.

The webinar will: - Explain the principles of traffic engineering and how primary and failover paths can be predetermined to guarantee less than 100 µs failover times. - Show how the deny-by-default architecture of SDN enables far more secure networks.

In this webinar, you will learn about the benefits of having fast and reliable arc-flash protection, as well as the pros and cons of different arc-flash detection methodologies.

In this webinar, the presenter will review a number of time-domain protection techniques, including directional elements, direct-tripping underreaching elements, and differential elements, that significantly speed up line protection.

In this webinar, we will address: • Bridging the gap between second, millisecond, and microsecond accuracies • Maintaining time accuracy by implementing best practices • Adding precise-time redundancy and mitigating GPS vulnerabilities.

The following list contains the topics that will be covered during the webinar: • NERC CIP-007-5 • NERC PRC-005-2 • RTAC Configuration

This webinar provides an overview of TWs and TW fault location capabilities in the SEL-411L and presents real-world field experiences using the SEL-411L.
