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

 

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.

 

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.

 

Tube style sensors are used where a conductor can be threaded through and clamped to the stainless steel tubes, ideal for many substation applications.

 

Busbar style sensors are fitted with standard 2 or 4 hole NEMA pads, ideal for many substation applications.

 

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.
