How to Solve Distribution Protection Challenges With Advanced Recloser Controls
Date held: July 25, 2018
Learn how you can use SEL’s modern digital recloser controls to solve protection challenges that have historically been treated as acceptable anomalies. We give examples of how to use records and events captured from these advanced controls to analyze protection challenges and identify the root cause. And for each problem identified, we share solutions that use advanced recloser control features, such as voltage detection, timers, and programmable recloser logic, to redirect the actions of the recloser. The challenges discussed in this webinar include:
Fast curve operations due to inrush.
Coordination of multiple time-overcurrent devices with limited time-coordination space.
Feeder relay operation caused by conductor slap.
Re-energization of faults in noncommunicating loop-restoration schemes.
