MICATU's Groundless Sensors

The MICATU Groundless Optical Current and Voltage Sensors are contact-free solutions for accurate current and voltage measurement, even when an external ground is unavailable or unfeasible. Platform with the m410B Optical Signal Processor to aggregate real-time, seamless delivery from any MICATU Optical Sensor models.

Designed for direct installation in air-insulated, pad mount equipment or within enclosures, MICATU Groundless Sensors provide a more reliable measurement across multiple voltage classes. With contact-free, optical sensing technology, MICATU Groundless Sensors can be deployed directly on a busbar or underground cable without the need for additional insulators. And the highly precise data is available on any connected SCADA network, thanks to the plug-n-play m410B Optical Signal Processor.

When used in a feeder compartment, MICATU Groundless Sensors do not require an external ground. It uses the compartment itself for ground reference.

Our Products

MICATU Optical Sensors are non-contact and utilize a 100% "all optical" measurement platform for unparalleled accuracy and precision of current and voltage readings, across multiple voltage classes. Sensor models are specifically designed for installation directly on busbar and/or feeder cables or on pad-mount equipment. 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.
