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.

Our Products

The MICATU 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.
