What b2 electronics GmbH does

b2 electronics GmbH is an Austrian privately held manufacturer founded in 2001 in Klaus (Vorarlberg) by Ing. Stefan Baldauf and Ing. Rudolf Blank, joined in management by Bernhard Baumgartner. The company designs and builds compact, lightweight Very Low Frequency (VLF) high voltage test equipment for medium-voltage and high-voltage energy cables, paired with partial-discharge (PD) and Tan Delta (TD) diagnostic add-ons and a portable breakdown analyzer (BA) line for transformer insulating oil. The portfolio spans VLF cable test sets from 28 kV up to 200 kV (HVA series, including TD-integrated variants), VLF diagnostics systems (PD30-E, PD60-2/PDTD60-2, PD90-2/PDTD90-2, PD120-2/PDTD120-2, PDTD68, PDTD200-2), standalone Tan Delta units (TD60-MC, TD90-MC, TD120-MC), BA75/BA80/BA100 oil testers, and supporting software (b2 ControlCenter, b2 Suite v2, BA ControlCenter v4). Core technology is a solid-state, dry-system VLF architecture without oil or arcing contacts, with integrated safety features such as the Dual Discharge Device (DDD), IP67 rugged enclosures, and Simultaneous PD & TD measurement to avoid cable pre-conditioning; the company self-describes as market leader for compact and lightweight cable test and diagnostics equipment, backed by an extensive patent portfolio.

The company is a subsidiary/independent member of the OMICRON group since 2019 and acquired High Voltage Diagnostics Inc. into the b2 group in 2023. b2 electronics sells to power grid utilities and cable testing service companies operating MV/HV networks, as well as to technical professionals (test engineers and decision-makers) who need training on MV/HV equipment operation. The portfolio is ISO 9001-certified since 2009 and complies with IEC 60156, IEC 60270, IEEE 400.2-2013, ASTM D1816, ASTM D877, and GOST 6581-75 standards, indicating global sell-ability.

Revenue is generated through three streams: (i) hardware sales of VLF testers, diagnostic systems, and BA oil testers manufactured in-house in Austria; (ii) professional training services for test engineers and technicians, delivered at the Klaus headquarters or on customer sites (e.g., a 2-day VLF course priced at EUR 1,450 per participant at Bad Kreuznach); and (iii) equipment rental services (including a Kabeldiagnose-Transporter cable-diagnostic van) operated through the German subsidiary in Cologne. Go-to-market is a hybrid sales-led and channel model: direct sales from the Austrian headquarters, a wholly-owned German subsidiary handling the German market end-to-end, and a sales partner network spanning more than 80 countries reaching customers in more than 120 countries. The company has roughly 65 employees of international background, runs an apprenticeship program with OMICRON electronics GmbH (recognized as an "ausgezeichneter Lehrbetrieb" by WKO and AK), and actively exhibits at industry events such as Cigré, Middle East Energy, and Expo & Forum. No financial figures (revenue, ARR, or unit volumes) are publicly disclosed.
