Underground Sensors
The Underground Optical Sensors capture the full range of measurements: current and voltage, temperature, and current harmonics and voltage harmonics, more accurately and precisely than any traditional solution. In addition to being completely modular, they're safe and fast to deploy to the field.
Connect to the m410B Optical Signal Processor for real-time access to a wider range of metrics for powerful analytic data today and beyond.
Safe
Because optical technology measures with light, it does not pass dangerous electrons. As a result, Gridview Sensors pose no violent failure or electrocution risks.
Accurate
Even in the most complex environments, Gridview Sensors maintain +/- 0.5% accuracy across the entire measurement range, regardless of applied voltage or current.
Advanced
The injection-molded HCEP housing is lightweight, durable, and non-conductive. The all-optical design keeps the sensor isolated from the current, ensuring high reliability and long life.
Easy Install
A typical three-phase system can be completed in about 3 hours. Voltage sensors are installed on any elbow, while the current ring sensor (model REC220 only) can slide over either a cable or busbar. Fiber optic cables connect the sensors to the m410B Optical Signal Processor.
Our Products
The GridView™ Medium Voltage & Current Sensor System utilizes a 100% “all-optical” measurement platform for unparalleled accuracy and precision of both voltage and current across multiple voltage classes. Installation time for a typical three-phase system is less than three hours, resulting in significant deployment savings. All signals from the sensor are connected via optical fiber connections to a “plug & play” modular optical sensor platform m410 Modular Optical Sensor Platform that is fully ruggedized and scalable.
