Na een start als DG Instruments GmbH in 1986 heeft de Power Diagnostix Groep een respektabele reputatie op het gebied van speciale meetapparatuur en bewakingssystemen voor hoogspannings- en hoogstroomapplicaties opgebouwd. Sinds de introductie van de PD meters begin 1993 werden ca 4000 deelontladingsmeters verkocht. Sinds juni 2019 maakt Power Diagnostix deel uit van de Megger Group.

Our History

Founded in 1986 as DG Instruments in Aachen, the company's innovative ideas lead to healthy growth in the following years. In 1999, Power Diagnostix moved to the then newly erected office building at Bruesseler Ring. Offering plenty of space in the beginning, in the meantime, due to steady growth in production and turnover, the space offered by this building, increasingly limited further expansion.

Old company building at Bruesseler Ring

Thus, in early 2007 decision was made to again erect a new company building at Vaalser Strasse, whose construction started in autumn 2008, and moving to the new site took place December 2009. The new office building, a six-story solitaire of 26m height, offers more than 2000m² space and greatly improved our possibilities. Nevertheless, the further growth of Power Diagnostix’ business during the next years again required more space. Thus, construction of another building behind our existing one started in May 2014 and was completed in May 2015 providing a work space of more than 4500m².

During the past three decades, Power Diagnostix grew steadily and established an increasing network of agents and representatives worldwide. Please contact us to get in touch with our representative in your area.

By June 2019 Power Diagnostix has been acquired by Megger (, a leader in electrical test and measurement globally for 130 years. Being part of the Megger group ensures a long term continuity for our business and provides access to Megger design concepts which can be utilized within our already very successful product ranges, while the extensive Megger sales network will ensure that our diagnostic equipment, test services and online monitoring expertise becomes increasingly available around the world.
