From an engineering office to a full-service provider

For 50 years, we have been a reliable service provider for customers in the energy supply and industrial sectors as well as in transportation, plant engineering and mechanical engineering. Over the past 25 years, we have developed from an engineering company for electrical and energy technology into a full-service provider in the power quality sector.

What company founder Frank Nosswitz still had to fathom with single-phase meters and paper recorders in the early 1980s is now done by an extensive pool of state-of-the-art power analyzers. Together with modern simulation software, we are thus able to thoroughly analyze and document any existing or planned power supply grid.

With a team of specialists and modern know-how, we carry out power quality analyses worldwide, plan and install solutions to optimize the electrical energy supply on site.

Partnerships with internationally active power quality companies make us part of the global power quality community.
