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.

Lindsey GEN2 sensors make a splash at IEEE PES in Denver, “IEEE PES T&D Show Blog: Half the Weight, Twice the Accuracy”.
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:

Multicore-style design sensors allow the conductor to be lifted into the sensor, eliminating the need to cut the conductor or make a jumper. Sensors of this style that include current measurements are not recommended for applications where sensing harmonics is required.
Busbar style sensors are fitted with standard 2 or 4 hole NEMA pads, ideal for many substation applications.
Tube style sensors are used where a conductor can be threaded through and clamped to the stainless steel tubes, ideal for many substation applications.
Clamp-top style sensors are tube style sensors that can replace any horizontal or vertical line post insulator. There is no need to cut the conductor, as a jumper passing through the sensing tube provides current sensing.
SVMI (standard voltage monitoring insulator) style sensors are smaller diameter voltage–only sensors intended for applications where voltage sensing may be required on both sides of a recloser or distribution switch. They are also ideal for use where higher accuracy is required than that provided by built-in capacitive voltage dividers.
