Autoreclosing Based on Fault Location—Cost-Effective Solution for Hybrid Lines With Overhead and Underground Cable Sections
Date held: December 7, 2017
Recorded webinar

Additional Information:

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.

Improve Distribution System Reliability With Automation
Date held: October 12, 2017
Recorded webinar

Additional Information:

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.

New Eyes for Distribution Make Protection Faster and Smarter
Date held: August 30, 2017
Recorded webinar

Additional Information:

Historically, distribution protection relied on coordination delays to trip the correct line during a fault. New technology now allows us to determine the location of a fault on a distribution feeder fast enough to actually influence protection decisions while the fault is happening. This gives us the opportunity to eliminate many of these delays and trip distribution systems faster and more effectively.

Simplify Digital Secondary System Design Using SEL TiDL Technology
Date held: August 2, 2017
Recorded webinar

Additional Information:

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.

Achieving Deterministic Communications Over Ethernet WAN for Mission-Critical Applications
Date held: July 26, 2017
Recorded webinar

Additional Information:

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).

Power System Big Data Challenges
Date held: May 17, 2017
Recorded webinar

Additional Information:

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.
