UE 4Site Online Monitoring Solutions

When electrical systems such as switch gear, transformers, insulators or disconnects and splices fail, the results can be catastrophic. The average cost of a critical electrical asset failure is greater than $500K per event and with the aging equipment and less than 5% of critical electrical assets have continuous monitoring integrated, the time is now to efficiently monitor your critical electrical assets for the three common failure modes, arcing, tracking & corona.


Always Listening. The 4Site is listening in real-time for the first sign of high frequency sounds produced by arcing, tracking & corona. Non-Invasive. Utilizing the power of airborne ultrasound, there is no contact with the electrical components of the equipment being monitored, making installation safer and easier. Optimized Data. The 4Site is designed to reduce data overload and alert by exception. While the 4Site is always listening, it will only transmit informative data if a threshold is crossed and eliminating the need to transmit healthy data. Scalability. Each 4Site is designed to monitor up to 4 locations simultaneously in one unit. We don’t just sell products, we offer a fully comprehensive service to compliment your maintenance program.
