Transmission Sensor—Detect solid dielectric cable failures in underground transmission cables from 69 to 230 kV in concrete-encased duct banks.

Troubleshooting—Determine if the fault is located in the underground cable to know if you can safely reclose on the circuit.

Splicing Applications—Monitor underground splices using a short-haul multimode fiber up to 250 meters. Monitor cable sections between vaults or underground-to-overhead transitions using long-haul multimode fiber.

Harsh Environment Applications—Install the SEL-8315 in harsh environments. It is submersible in up to 15 feet of water and can operate in extreme temperatures.

Safety—Reduce arc-flash risks to line crews by eliminating the need to open high-voltage enclosures or enter subsurface vaults during fault-finding patrols.

Fast Fault Location—Integrate with new or existing RadioRANGER Underground Wireless Fault Indication Systems and quickly locate faults. There is no need to open, enter, pump, or drain multiple vaults or utility access covers to determine fault status. Troubleshooters can use the information displayed on the remote fault reader to find the faulted cable section, in many cases without leaving the truck.

Details

Locates Faulted Cable Sections Quickly
Locate cable failures within and between cable vaults using easy-to-install SEL-8315 Fault Indicators.

Operates in Harsh Environments
The SEL-8315 Fault Indicators are submersible in up to 15 feet of water and can operate in extreme temperatures.

Communicates Using Own Power
No external power source is required.

Works With Existing RadioRANGER Installations
The SEL-8315 plugs into the SEL-8300 RadioRANGER Wireless Interface and reports to the interface any out-of-phase condition. You can then use the SEL-8310 RadioRANGER Remote Fault Reader to remotely read the status of the fault indicator.

Some configurations, such as those with an LED or timed-reset feature, may contain a battery. For configurations with a battery, please see the lithium metal battery warning.
