EA Technology UltraTev Plus2 – Advanced Partial Discharge Monitor
Protecting high-voltage networks has never been more important. The EA Technology UltraTev Plus2 is a next-generation partial discharge monitor designed to give engineers and asset managers clear insight into the condition of their equipment. Portable, rugged and easy to use, this powerful tool helps identify issues before they develop into costly or dangerous failures.

Why Choose the EA Technology UltraTev Plus2?
The UltraTev Plus2 is a hand-held instrument that combines tried-and-tested partial discharge detection methods with modern digital analytics. Unlike older PD test tools, it can differentiate genuine PD activity from background noise or electrical interference. This means results are more reliable, allowing better decisions to be made on maintenance, repair, and replacement.
For network operators, early detection of PD helps avoid outages, reduce repair costs, and extend the life of critical assets such as switchgear, transformers, and cables. Case studies show the UltraTev Plus2 preventing serious failures at solar farms, ports, and major industrial printing sites.
