Piedmont Bushings & Insulators, LLC offer three voltage classes of economical Power-Line Sensing. Our designs offer a "No Line Cutting" installation with linear outputs up to fault levels in a proven homogeneous insulation system.

Line Post Sensors

PB&I line sensors were designed with the lineman in mind, utilizing a lay-in primary conductor groove and swing link primaryPBI Line Sensors  clamp. You can install our sensor without cutting the line or using primary taps all without interruption of customer service.

Our shielded, non-inductive resistive divider provides linear output voltages proportional to primary voltage to ground over temperature, aging proximity effect or weather conditions. Low voltage AC outputs can be open-circuited, or shorted without damage, and the sensor is designed to keep high voltages from being impressed onto secondary leads.

In addition to standard tests required on each sensor, every Piedmont Bushings and Insulators, LLC sensor is tested for partial discharge up to 125% of maximum operating voltage to insure that the insulation system our in house design specification of >2 picocoulombs of discharge at 125% of maximum operating voltage.


So, if you're looking for a time tested proven line sensor please contact us for Piedmont Bushings & Insulators to see how we can help you with your line sensing needs.
