Micatu's RNC125 Groundless Sensor

The Gridview Groundless Optical Voltage Sensor is a contact-free solution for accurate 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 Gridview Sensor models.

Designed as a direct replacement for standard Neon "Voltage Presence" visual indicators, the Gridview Groundless Sensor provides a more reliable measurement across multiple voltage classes. With its contact-free, optical sensing technology, the RNC125 can be deployed directly on a busbar or underground cable. 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, the RNC125 does not require an external ground. It uses the compartment itself for ground reference.

Our Products

The GridView Non-contact 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 directly on busbar and/or feeder cables. 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.



  • Voltage: 4kV to 25kV
  • Amperes: N/A
  • Weight: .9 kg (2 lbs)
