The ability to acquire accurate data from critical points throughout the underground medium voltage (MV) distribution network is a key requirement for enhancing the reliability and efficiency of the grid. The sensored termination is designed to provide highly accurate voltage and current data through simple retrofits of existing power equipment, such as switchgear and transformers. The termination provides data that can enable real-time monitoring and control and automation capabilities throughout the underground MV distribution network.
The sensored termination from 3M offers the following advantages:
- High accuracy: Provides a pathway to the conductor within the shielded cable, delivering accurate voltage and current waveforms in real time.
- Quick and easy installation: Compact, one-piece mechanical and electrical connection requires minimal downtime to install. Cold shrink technology allows simple, fast, reliable installation without the use of special tools, sealants, adhesives, torches or other heat sources.
- Factory calibration: The sensor is pre-calibrated and factory tested to ensure maximum reliability. No field calibration is required to maintain accuracy levels.
- Allows easy retrofits: Enhances current infrastructure by adding measurement functionality to existing power equipment.
The sensored termination is designed for indoor applications that utilize a livefront form factor. Customers can call (512) 984-5193 for more information or visit
