Underground Sensors

Lindsey offers a complete range of current and voltage sensors for 200A and 600A pad-mount, metal-clad, underground, and submersible applications. When automating legacy pad-mount or underground switchgear without auxiliary power availability, Lindsey’s patented underground power supply installs quickly to provide a source of DC power for meters, radios, controls and RTUs.

High accuracy voltage (0.5%) and current measurements
200A ANSI load-break elbow and tee-body voltage sensors can also be used on 600A cable systems with a reducing well.
Cast-in cable option for submersible applications
Split-core current sensor provides installation flexibility
Ring-type current sensors are water tight and suitable for submersible applications
Underground power supply is fully submersible and provides 12VDC power with various ride through options.

200A Voltage Sensors

Lindsey 200A voltage sensors are available at 15kV and 25kV in both IEEE 386-type elbow and T-body connectors for simple, fast, and flexible installation.
