Underground Sensors

Lindsey introduces three new sensors for underground / enclosed applications.

Type LVS Voltage Sensor for use in space constrained live-front switchgear applications.

Type UOV Voltage Sensor for use in MV oil-filled electrical equipment.

Type 9561 Voltage Sensor for use in low voltage (up to 1000 VAC) switchgear applications.

Lindsey offers a complete range of current and voltage sensors for pad-mount, metal-clad, underground, oil-filled, SF6, 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% or 0.3% metering accuracy)
  • High accuracy (1% or 0.3%) current measurements
  • 200A ANSI load-break elbow and tee-body voltage sensors can also be used on 600A cable systems with a reducing well.
  • Voltage sensors for oil-filled and SF6 insulated switchgear
  • Low voltage switchgear voltage sensors
  • 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.
