Raytech

What Raytech does

Raytech AG is a privately held Swiss manufacturer of precision test and measurement instruments for the international power industry, founded in 1995 and headquartered in Bremgarten, Switzerland. The company designs, develops, manufactures and tests its full product range at its Swiss headquarters, and sells through a wholly-owned U.S. subsidiary (Raytech USA Inc., established 1996 in Perkasie, PA) and a global network of authorized representatives covering more than 30 countries across Europe, Asia, the Middle East, Africa and the Americas.

The product portfolio is narrowly specialized around power transformer diagnostics and includes 3-phase and single-phase turns ratio meters (TR4, TR-MARK III series, TR-1/TR-1P), winding resistance meters at 15A to 100A output (WR14, WR50 and WR100 series, in field and rack configurations), capacitance and tan delta/power factor meters (CAPO 2.5 and CAPO 12), micro-ohm meters (Micro Centurion II, Micro Junior 2), a current transformer tester (CT-T1), and two automated transformer observation systems (ATOS and the portable mini-ATOS). Underlying capabilities include an integrated automatic multiplexer, dynamic resistance measurement (DRM), frequency response of stray losses (FRSL), heat run testing (HRT), voltage and frequency sweep diagnostics, and an integrated safety unit (ISU-R). Software offerings comprise T-Base Pro and T-Base Lite for remote control and data management, an optional paid SDK for custom instrument integration, and legacy Toolbox.NET utilities.

Raytech monetizes the platform through capital-equipment hardware sales, optional paid firmware licenses for advanced features (FRSL, HRT, DRM, PST), and software licenses, with prices quoted on an inquiry basis rather than published. Customers are B2B engineering and field-service organizations: electric utilities and power generation companies, third-party transformer service companies, and transformer manufacturers using the instruments for installation, commissioning, maintenance and failure diagnostics. Marketing relies on a content-driven website, an email newsletter, and the regional representative channel, with no disclosed direct e-commerce.
