GridView™ Standoff Insulator Voltage Sensor - Ri125

The GridView™ Standoff Insulator Voltage Sensor is a direct replacement for standard resistive voltage divider sensors. Because of the “all optical” sensor design, there are no conductive materials used in the measurement of voltage as well as the transmission of the optical signals. The insulator body is cast in hydrophobic cycloaliphatic epoxy (HCEP) using a state of the art injection molding process. HCEP construction provides superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet or humid conditions. All calibration and performance settings are stored in the ruggedized modular electronics enclosure at the base of the optical cable. When integrated with the (m410) Modular Optical Sensor Processor, this provides for a “highly accurate” as well as “low cost” precision solution for distribution grid monitoring and control.


Features include:

All optical Solution for Voltage Measurements:

Ri125: One SKU for 4kV to 25kV Voltage Classes

Ri135: One SKU for 4kV to 35kV Voltage Classes

Four ½-13 UNC mounts on top and bottom

Calibration and offsets are contained within the Ri125 Sensor

Benefits of HCEP:

– Enhanced water shedding properties

Reduced contamination-related leakage

Improved product quality and reliability

– Improved UV protection

The GridView™ Standoff Insulator Voltage Sensor, utilizes a 100% “all optical” measurement platform for unparalleled accuracy and precision of voltage readings, across multiple voltage classes. Specifically designed for installation in masonry switchgear, air insulated switchgear (AIS) and for any phase to ground busbar measurements. All signals from the sensor are connected via optical fiber connections to a “plug & play” (m410), Modular Optical Sensor Platform, that is fully ruggedized and scalable.
