What HV Diagnostics does
HV Diagnostics Inc. is a privately held manufacturer of high-voltage electrical test equipment headquartered at 271 Rope Mill Parkway in Woodstock, Georgia. Founded in 1992, the company has operated for more than 33 years and positions itself as a leading North American supplier of field-proven VLF (Very Low Frequency) and DC hipot testers, cable diagnostics systems, cable fault location instruments, and dielectric oil testers. The core technology stack centers on the HVA Series of oil-free, load-independent sinusoidal VLF/DC instruments spanning 28kV to 200kV output capacity, integrated with companion Tan Delta diagnostic modules (TD30 through TD120-MC) and Partial Discharge systems (PD30-E, PD60-2/TD, PD90-2/TD, PD120-2/TD), plus the proprietary Digi-Bridge bridge-method fault locator and Tracker Pro time-domain reflectometer.
The company's revenue model is anchored on quote-based direct enterprise hardware sales supported by an in-house field sales organization targeting North American electrical utilities and wind/solar farm operators, with secondary verticals in industrial facilities and electrical service contractors. Recurring and project-based revenue streams diversify the model: on-site cable testing and fault-location services, short-term equipment rentals, NIST-traceable repairs and annual calibration, and association-approved training programs. Pricing is not publicly disclosed, but the spec floor-to-ceiling ($30k-ish portable units up to six-figure trailer-mounted transmission systems) indicates a transactional enterprise sale with multi-product pull-through via the HVA platform. The company is ISO 9001:2015 certified (certificate HVD-3883US24-25), maintains CE marking on select products, and operates with 1–10 disclosed employees while actively recruiting field technicians.
