OVERVIEW
The SEL-8301 Underground Distribution Sensor is designed to optimize outage management and improve underground reliability. With a line current measurement accuracy of 1.5 percent, it allows for more effective switching decisions, letting you restore power to more customers. Using a wireless network, the SEL-8301 sends fault, load current, and water depth information to your control center for efficient dispatching of repair crews and reduced outage durations. The flexible design makes the SEL-8301 ideal for underground vaults, pad-mounted switchgear and transformers, and high-rise distribution feeders and transformer rooms.
• Line current measurement accuracy of 1.5 percent allows for more effective switching decisions and faster power restoration to customers during an outage.
• Energy harvesting provides up to 20 years of maintenance-free operation.
• Submersible design reliably operates in up to 15 feet of water to ensure delivery of status information in harsh conditions.
• Flexible design supports up to 12 phases with one device.

OVERVIEW
The SEL WSO-11 Wireless Sensor for Overhead Lines helps personnel locate faults quickly and easily by monitoring distribution circuits for faults and outages. Users can periodically log circuit load data for system analysis and remotely monitor the system via the On-Ramp Wireless RPMA® (Random Phase Multiple Access) Network. The WSO-11 includes the following additional features:
• Event Detection. Improve system reliability by remotely monitoring overhead distribution circuits for faults and outages.
• AutoRANGER® Trip Logic. Account for load variations throughout the entire system with the auto adjusting trip threshold logic.
• Extended Current Range. Install the WSO-11 on distribution circuits with load current from 0 A to 600 A.
• Long Battery Life. Avoid costly maintenance with a battery life of over 14 years.
• Network Connectivity. Deploy the WSO-11 as part of the SEL Wireless Distribution Fault Indication System to report faults on overhead circuits quickly and remotely.
• Field Upgradeable. Perform over-the-air software updates.
• 5-Year Warranty. Take advantage of an industry-leading 5-year warranty.
