HV Technologies

What HV Technologies does

HV Technologies (HV TECHNOLOGIES, Inc.) is a privately held US company founded in 1998 and headquartered in Manassas, Virginia, with a supporting European office in Zeiningen, Switzerland. The company manufactures, sells, repairs, and installs high voltage (HV) and electromagnetic compatibility (EMC) test equipment, and functions as the exclusive US distributor for several European manufacturers including Haefely, EMC Partner, Schwarzbeck, Frankonia, Montena, and Prana. Its customers span power utilities, power apparatus manufacturers, aerospace and defense firms, and electronic equipment producers, with named accounts including Eversource, Collins Aerospace, BAE Systems, Bonneville Power Administration, Okonite Company, and Hitachi Energy. HVT is led by three generations of the Bolliger family and operates with approximately 15-20 employees, supported by ISO 9001:2015 quality registration and ISO 17025:2017 A2LA accreditation for its calibration laboratory.

The company's product portfolio is organized into two lines. The HV test equipment line covers cable testing, partial discharge testing, tan delta/power factor testing, impulse testing, transformer testing, and calibration equipment. The EMC test equipment line covers transient generators, RF immunity test systems, military and avionics test equipment, RF power amplifiers, fiber optic links, and monitoring systems. New product introductions between 2024 and 2026 include the HiAS 744 Impulse Analyzing System, DDX 9160/9161 PD & RIV Detectors, EMC Partner IMU Series modular immunity test generators, HVC 300 impulse generator control, MOL25T/MOL500T fiber optic links, EMC Partner ESDEX ESD Gun, and AVI-LV5 indirect lightning test system. Products are positioned to support compliance testing under IEC, IEEE, ANSI, UL, MIL-STD-461, and RTCA DO-160 standards.

HVT's business model combines branded hardware distribution with value-added services. Revenue is generated through capital equipment sales of HV and EMC test systems, complemented by installation, commissioning, calibration, repair, upgrade, and training services delivered through an accredited laboratory. Pricing is quote-based, typical of capital equipment sales into regulated industrial customers, and the go-to-market is B2B enterprise field sales targeting utilities, power equipment manufacturers, aerospace and defense primes, and government agencies. Long-tenured exclusive distribution partnerships with European manufacturers are the primary differentiator and the principal source of competitive insulation.
