Engineering servicesand world trading inHigh Voltage Components
A small, senior consultancy network founded in 2008. We design, review, test and diagnose the components that move power across grids — transformers, GIS, switchgear, bushings.

Forty years of high-voltage engineering, distilled into an independent practice.
We started in 2008 when Dr. Fracchia founded the company in Italy after 30 years working in the High Voltage field.
Our business is focused on every kind of High Voltage component — including Power Transformers, GIS, Switchgear and High Voltage Testing Equipment — covering specifications, design review, testing, diagnostics and fault analysis.
For Power Transformers we offer a complete package, covering every aspect of the component: design, life management, maintenance.
We are integrated with two sister companies: HV Trafo Solutions, based in Romania, and Energy Solutions International, based in Perú.
A senior bench, measured by what it has touched.
Five disciplines, one engineering culture.
We cover every technical aspect of High Voltage components: specifications, design review, testing, manufacturing inspections, life assessment and failure analysis.
