Voltage Sensing Standoff Insulators

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.

Standoff insulator-style sensors are interchangeable with porcelain standoffs with a 3 inch bolt circle.
