Segmenting overhead lateral lines with multiple automation devices in series provides end-to-end protection and enables a smart grid in the truest sense —one that automatically responds to faults to mitigate and minimize outages, keeping more customers online and happy.
Why Segment Lateral Lines
Lateral lines often take a back seat to upstream system upgrades. But given their extensive reach, modernizing them can have a deep impact on your grid.
Upgrading from the head of the lateral to the grid edge with automated technology can significantly:
- Improve reliability and resilience
- Accelerate restoration times
- Increase customer satisfaction
Where to Segment
The key to curbing outages for widescale benefits and reducing O&M expenses is strategically segmenting in key areas with coordinated devices.
Overhead Laterals
TripSaver® II Cutout-Mounted Recloser
Prevents up to 80% of issues from becoming sustained outages by testing for faults and restoring power automatically if they are temporary.
Alternative to Fuses & Hydraulic Reclosers
- Available in 200-AMP, 100-AMP, and 40-AMP options to move reclosing closer to fault
- Limits sustained outages to the faulted lateral, protecting upstream customers
- Vast, configurable protection settings for easy system integration
- Decreases costs by avoidng re-fusing errors, frequent maintenance trips, and the need for excess inventory
Far Grid-Edge Overhead Laterals
VacuFuse® II Self-Resetting Interrupter
A durable transformer fuse replacement that also offers fault-testing to deliver grid-edge protection for customers in the most vulnerable locations.
Alternative to Transformer Fuses
- Prevents faults toward the end of the lateral from affecting upstream customers
- Local data visibility and communications operational down to 1 A of load current
Underground Laterals
EdgeRestore® Underground Distribution Restoration System
When deployed on a looped circuit, the EdgeRestore system automatically locates and isolates faults and restores power.
Alternative to Manual FLISR Operations
- Sectionalization and isolation of underground faulted cables
- Reroutes power from an alternate source in under 60 seconds without crew intervention
- Fits into existing protection schemes and transformers
- TripSaver II reclosers add automatic restoration capabilities from the head-end riser poles
