Standoff Insulator Voltage Sensor
High-accuracy standoff insulator-style voltage sensors are flat through the 20th harmonic and are available in hi-pot versions. Sensors are interchangeable with porcelain standoffs using standard 3-inch bolt circles
Product Overview
The Lindsey Voltage Monitoring Insulator (VMI) is designed to be interchangeable with ordinary standoff insulators in either indoor or outdoor applications. They may be installed indoors or in cabinets as a bus support in vertical or horizontal orientation. Brackets are available to mount VMI’s outdoors on crossarms or existing switchgear. The VMI is not designed or intended to support conductor load and is not a replacement for a line post insulator.
