The company

Ing. Hubert Bachl-Hesse e.U. (hbconsult) was founded in August 2016 as a private company, located in 1210 Vienna, AUSTRIA.

The company‘s objective is to provide high quality, customer oriented and practical services.

Personal information

I was born in Vienna in 1965 and graduated as an electrical engineer at Höhere Technische Lehranstalt, TGM in Vienna.

My professional career started in 1985 as a test engineer and continued as head of testing and quality manager at Cooperative Testing Institute – CTI-VIENNA. During that time I also got involved in measurements and assessment of the body impedance of humans and life stock.

In 1993 I changed to EH-Schrack Components AG as head of research and development department, being also responsible for approbation matters and patent affairs.

By end of 1994 I returned to CTI-VIENNA and took over the Technical as well as the General Management of the company.

Between 2007 and 2013 I was a member of the board of directors of the Electrical Safety Foundation – ESF-VIENNA.

In 2016 I resigned from my functions at CTI-VIENNA and founded my own company as consulting engineer being a Member of the Austrian Association of Consulting Engineers and as a certified expert for low voltage electrical installations, protective measures, earthing, overvoltage protection and switchgear.

My special areas of expertise are overvoltage protection and protective measures in electrical installations and for equipment. In this area I am also convenor and member of various national and international technical committees at OVE, CENELEC and IEC.
