Advanced Technology for Added Segmentation Using New Fault Finding Technique

 Reliability metrics on duration improve by reducing outage length and limiting the customer’s impacted. Working with Roanoke REC, we will discuss the difficulties of adding circuit protection points that break feeders into smaller segments. Based on a pilot installation, the cooperative was able coordinate to up to 6 Intellirupter segments, using only one TCC curve. Response to low available fault current along extended length lines, typical at many RECs was not compromised. Other automation and protection benefits will be discussed.
