What ohv diagnostic does
ohv diagnostic GmbH is a privately held German company headquartered in Dresden that designs, manufactures, and sells high-voltage test and diagnostic equipment, complemented by on-site diagnostic services, training, and certified calibration. Founded in 2013, the company has specialized exclusively in condition assessment of medium and high-voltage electrical assets, serving energy grid operators, power generation companies, and industrial power users across 45 countries with 363 customers and 5,632 secured assets.
The company's core product portfolio centers on four technology pillars: DAC (Damped AC / Oscillating Wave Test System) cable testing systems (models M30/M40, M60, H200, H300) for cable commissioning and condition assessment; PDD portable partial discharge detectors for field measurements; PDM continuous monitoring systems (PDM-2, PDM-4, PDM-Combi) for transformers, generators, switchgear, and cables; and software suites (DAC Suite, PDD Suite, PDM Suite, ohvSuite Remote Support) for data analysis, alerting, and remote diagnostics. The product ecosystem also includes specialized UHF, HFCT, ultrasonic, and bushing sensors, coupling and calibration accessories, and custom/OEM device development. The company additionally distributes Globecore oil testing products and Haefely high-voltage testing equipment as the exclusive sales partner in German-speaking countries.
Revenue is generated through a mix of proprietary hardware sales, professional services (on-site diagnostics, commissioning, installation, consulting, and training), certified calibration, custom/OEM development, and an emerging recurring software/subscription component via software activation licenses and remote monitoring subscriptions. The go-to-market is enterprise field sales targeting utilities, transmission and distribution system operators, and power generators globally, supported by a network of 50 partners worldwide and a direct sales team led by a dedicated sales manager in Dresden.

- HIGHVOLT Prüftechnik Dresden: HIGHVOLT, also based in Dresden, develops HV testing systems for cables, transformers, and switchgear, offering overlapping capabilities with ohv's DAC H200/H300 product line for HV cable commissioning and diagnosis.
Broad incumbents
- Qualitrol: Qualitrol is a broad incumbent offering monitoring and diagnostics for transformers and other substation assets; a competitor in the continuous monitoring space where ohv's PDM systems operate, but with a wider asset-class portfolio.
- Siemens Energy (Trench / Reyrolle): Siemens Energy and its Trench/Reyrolle units supply HV instrument transformers, switchgear, and integrated monitoring systems used by the same customers as ohv, representing a broad incumbent alternative for asset monitoring and HV diagnostics.
Emerging players
- B2 Electronics GmbH: B2 Electronics is an Austrian niche specialist in HV measurement, partial discharge diagnostics, and cable testing with overlapping product lines to ohv's DAC and PDD offerings, primarily serving DACH and select international utilities.
