What Ross Engineering does
Ross Engineering Corporation, founded in 1964 by Hugh Ross in Campbell, California, designs, manufactures, and tests high voltage electronic and electro-mechanical devices serving applications ranging from millivolts to 1,200 kilovolts. Its product portfolio spans four categories: HV Control (relays, vacuum contactors, switches, spark gaps, solenoid drivers, step-start systems), HV Measurement (voltage dividers, probes, voltmeters, megohmmeters, test loads), HV Isolation (coaxial cable drivers, toroids, corona nuts), and HV Safety (safety voltmeters, grounding rods, hotsticks). Technical differentiators include accuracies of ±0.01% DC on voltage dividers, bandwidths exceeding 20 MHz, pulse response to 10 nanosecond rise times, and voltage divider standards that received NBS/NIST transfer status in 1982 with no documented drift after thousands of hours. The company operates a 20,000 sq. ft. fully integrated facility in Silicon Valley with ISO 9001:2015 certification and ISO/IEC 17025:2017 A2LA-accredited calibration up to 450 kV PK 60 Hz and 400 kV DC, complemented by an in-house CNC and manual machining division for prototype and short-run work.
The business model is direct sales of precision engineered hardware to enterprise customers in power electronics, power utilities, laboratories and test facilities, industrial plants, aerospace, medical imaging, semiconductor manufacturing, radar, and particle accelerator segments, supplemented by A2LA-accredited high voltage calibration services and machine shop work. Products are sold both directly from Campbell and through a network of authorized representatives in 24 countries across North America, Europe, Asia-Pacific, the Middle East, South America, and Africa. Named end users include Lockheed Martin's Satellite Test Center and major US particle accelerators, and the company reports products in use at over 2,000 manufacturers, utilities, laboratories, and industrial plants worldwide.
Ross Engineering remains privately held and founder-led; Hugh C. Ross serves as President and Chief Engineer with no documented institutional investment, M&A activity, or external capital event. Revenue is not publicly disclosed, and pricing is quote-based with no published rates, consistent with a custom-engineering and contract-manufacturing posture. Customer engagement is sales-led and relationship-driven rather than marketing-led, with the company maintaining a static product website and no active social media or paid acquisition channels of record.

Its HV relays, dividers, and probes overlap directly with Ross Engineering's measurement and control portfolio.
Broad incumbents
- Schneider Electric: Schneider Electric offers HV and MV switchgear, protection relays, and power monitoring products globally. Its industrial control and HV distribution portfolio addresses the same end customers (utilities, industrial plants) as Ross Engineering, but at much larger scale.
- Eaton Corporation: Eaton manufactures electrical power management products including HV switchgear, contactors, relays, and power quality instruments. Its industrial control and switching portfolio overlaps with Ross's HV contactors, relays, and switches for industrial and utility customers.
- Siemens Energy: Siemens Energy supplies HV transmission and distribution equipment, including switchgear, instrument transformers, and grid protection systems. It competes with Ross's vacuum contactors, HV relays, and voltage dividers at the high-end utility and grid infrastructure level.
- ABB Ltd. ABB is a global electrification and motion leader offering HV switchgear, relays, instrument transformers, and grid measurement equipment. While far broader than Ross, ABB overlaps with Ross's vacuum contactors, circuit breakers, and HV measurement products in utility and industrial markets.
- Teslaman / TDK-Lambda High Voltage: TDK-Lambda (including legacy TDK-Lambda High Voltage division) produces programmable and OEM HV power supplies and modules for industrial, medical, and semiconductor applications. It competes indirectly with Ross via integrated HV power supply solutions incorporating relays and dividers.
Regional players
- PMK Mess- & Kommunikationstechnik GmbH: PMK is a German manufacturer of high voltage probes, oscilloscope accessories, and HV measurement solutions sold across Europe and internationally. As both a peer (HV probes and dividers) and Ross's authorized representative in Austria/Germany, PMK is a directly comparable competitor in the European market.
