For close to 20 years we have developed and manufactured VLF high voltage systems for cable testing and diagnostics, serving power utilities and their supporting industries worldwide.

HVA series - VLF (0,1Hz) test sets

b2 electronic offers a comprehensive range of VLF (0.1Hz) test sets (HVA series) from 28kV up to 200kV of remarkably small dimensions and weight. Our VLF test sets are dry-type test systems, which would otherwise require routine maintenance and limit operational time.

Tan Delta (TD) diagnostic system

The tan delta measuring instruments are available as external devices or as an integrated function in a HVA high voltage generator.

Partial Discharge (PD) diagnostic system

A new range of extremely easy-to-use Partial Discharge Devices complements the cable diagnostics portfolio.

Dielectric Oil test sets

Devices with a very fast switch-off time after flash over enables b2 Oil Test Sets to measure also modern silicon, mineral and ester oils without damaging the test sample.
