What High Voltage Test Systems does
High Voltage Test Systems (HVTS) is a French specialist manufacturer and servicer of high voltage testing equipment, founded in 1995 by Bruno Haas, who brought 16 years of director-level experience from Swiss group Haefely. Headquartered in a custom-built factory in Mulhouse, France, the company designs and produces new equipment including SGK Series impulse generators (200 kV and higher, with 5 or 10 kJ per stage) and proprietary control systems (C3000, C300, ICON 3000, GLP2) used for AC, DC, and impulse testing across a voltage range from 50 kV to 3200 kV. Complementary products include water terminations up to 600 kV, cable heating systems, Faraday shielded rooms with guaranteed 1 pC no-load ground noise performance, and control rooms. The underlying technology platform is built around specialized analog and digital control electronics for high voltage applications, with modular replacement controls that integrate with legacy equipment from Haefely, Passoni Villa, Hipotronics, Ferranti, and AEM.
The company's core revenue engine is the modernization, refurbishment, and aftersales support of legacy high voltage testing installations rather than solely new equipment sales. Following its 2008 acquisition of Passoni Villa's testing department from Alstom, HVTS holds exclusive official aftersales rights for Passoni Villa-manufactured impulse and DC generators. Revenue streams span new equipment sales, pre-owned equipment resale, equipment rental, turn-key laboratory projects, modernization services, spare parts supply, dismantling and relocation logistics, and operator training. Customers include major utilities (RTE, EDF), cable manufacturers (Nexans, Prysmian, Draka), and power equipment OEMs (Schneider Electric, Siemens, Alstom Grid, Areva, Westinghouse), with approximately 80% of revenue derived from international markets across 19+ countries on five continents. HVTS operates a direct B2B enterprise sales model with quote-based pricing, supported by a network of technology and co-development partners across Europe and the United States.
