TWS FL-8 & TWS FL-1 Single Tower Traveling Wave Fault Locator
Brand: Qualitrol Company
A device that provides extremely precise fault location on multiple lines enabling operation and maintenance engineers to respond rapidly to events and correct defects at minimum cost and maximum efficiency.
Features- Best accuracy to ± 195 feet [± 60 meters] independent of impedance methods
- Reduce downtime by getting to the fault site faster
- Track intermittent self clearing faults and focus maintenance at the right spot to prevent a major breakdown
- Accurate results from circuit trips automatically displayed in the dispatch center within minutes of the event
- Maintenance crews alerted by email notification
- Display, keypad and USB port allow more interaction with the device
- Modular, reliable hardware
- Flexible communications
