A Smarter and Safer Alternative to Manual Solutions

Each year millions of transformers need to be re-energized. Field personnel rely on mechanical solutions to know units are safe to re-energize.

The UbiGrid TFD+ is a better option.

It attaches to existing aerial and padmount transformers, and delivers real-time analytics on critical parameters, such as internal pressure, temperature, voltage, and GPS location over an LTE network. No more driving around looking for faults. Field personnel can now get critical safety and operational data, over the cloud, to prevent injuries, locate issues, and avoid needless transformer replacements.

Based on Proven Technology

UbiGrid TFD+ leverages UbiGrid Distribution Transformer Monitor Plus’ technology that has been proven at scale in some of the most reliable utilities in North America. UbiGrid TFD+ focuses exclusively on real-time transformer health data to ensure safer reenergizing, better asset management, outage prevention, and fast outage recovery with fewer trips to the pole.
