A mainstay in utilities, Lindsey sensors provide exceptionally reliable and highly accurate voltage and current monitoring for substation, overhead, pad-mount and submersible underground distribution applications.
Zero phase shift, superb harmonic performance and 0.5% voltage accuracy make Lindsey sensors ideally suited for Volt/VAR control, monitoring, and other distribution automation applications.
For transmission applications, the Lindsey TLM™ conductor monitor provides unparalleled insight into conductor behavior, including clearance-to-ground, temperature, current, and vibration through 765kV. The TLM seamlessly provides the critical data for Lindsey’s SMARTLINE™ dynamic line rating system.
The TLM monitor provides a complete picture of transmission conductor behavior in real time.
Medium voltage current and voltage sensing contained in familiar underground componentry.
Medium voltage current and/or voltage sensing contained within a fully mechanical rated post insulator.
Our initial line of medium voltage resistive voltage divider based voltage and current sensors, conveniently embedded into post insulators, have even become referred to as Lindsey sensors.
Hundreds of thousands have been installed over the past 25 years for good reasons:
Over the years Lindsey has taken this same measurement technology and extended it to medium voltage underground systems:
Lindsey’s legendary reputation in transmission equipment and sensors combine in the unique TLM conductor monitor. The TLM is specifically designed to provide the live data feed necessary for accurate and reliable dynamic line rating and documenting line clearance compliance.
Highly refined from initial development at the U.S. Department of Energy’s Idaho National Laboratory, the TLM monitor contains a variety of advanced technologies including LiDAR, magnetic field power harvesting, and encrypted communications. Combined with Lindsey’s decades of EHV experience, the resulting self-powered, corona-free, comprehensive sensor package is designed for fast, hot line installation up through 765kV.
