High voltage engineering
The expansion of energy grids and its equipments is a necessary step in times of energy transition. We are working for more than 10 years as a test laboratory with DAkkS accreditation and test high voltage equipment regarding actual norms and customer specific standards.
With our broad equipped test laboratory we offer you a wide range of test services and support in research, wether in our laboratory or on site.
