GEN2 Post Insulator Sensors

The Accuracy you need. The Reliability you want.

For over 30 years, Lindsey current and voltage sensing post insulators have been the standard for smart grid applications. Lindsey GEN2 line post sensors incorporate the same high accuracy and reliability of their Polysil® insulation-based for forbearers, while adding many subtle improvements to increase their utility.


New Lineman Friendly Features

  • Less than 1/2 the weight of Lindsey Polysil-based sensors.
  • Hotstick friendly conductor keeper* with washer-less bolts accommodates a wide range of conductor sizes.
  • Glove friendly cable with bayonet-style water proof connectors that “snap” when closed, eliminating over- and under-tightening.

* Patent Pending

GEN2 bayonet-style water proof connector
New glove friendly cable with bayonet-style water proof connectors that “snap when closed, eliminating over- and under-tightening. Sealed from the environment, the connectors are waterproof even if left exposed to the elements.

Advanced Performance Characteritics

  • 0.5% voltage accuracy, with flat harmonic response, and no phase shift. The high accuracy of GEN2 sensors make them ideal for today’s advanced metering and Volt/VAR-control applications where precise knowledge of feeder voltage is critical for economic success.
  • 1% current accuracy with no phase shift.
  • Voltage and current accuracy is independent of weather and conductor diameter.
  • Safe, low voltage, very low current outputs.
  • Hydrophobic cycloaliphatic epoxy construction provides superior performance in high pollution and wet environments.
  • 30% increase in leakage distance.
  • Physical construction that meets all the electrical and mechanical requirements of post insulators providing endless installation options.



Industry standard “Lindsey sensors” have provided the utility industry with exceptionally reliable voltage and current measurements for over 25 years. Highly accurate, with excellent frequency response and no phase shift, Lindsey sensors are embedded in a variety of full mechanical load-rated post insulator configurations provide endless installation options.

Hundreds of thousands of Lindsey’s line of medium voltage resistive voltage divider-based voltage and current sensors have been installed for good reasons:

  • Voltage only, current only, and combined voltage-current sensor models
  • High voltage accuracy (0.5% standard) provides the confidence needed for today’s demanding Volt and VAR control applications like CVR and VVO
  • 1% current accuracy
  • Mean time between failure (MTBF) exceeding 10,000 years means true install and forget reliability
  • No phase shift on voltage and current measurements
  • Versions available for demanding harmonic applications
  • Live line installation
