High-voltage equipment and installations 
Low-voltage equipment and installations
EMC testing
Crimp and screw connectors
Cables and lines
Three-phase electric power cable fittings
Insulating materials (oil analyses)

Additionally, our existing facilities and multitude of testing equipment offer many other testing opportunities. You are welcome to ask for them.

EMC laboratory

Electromagnetic compatibility of devices and components

innogy SE, Eurotest carries out EMC tests in the following areas:  

  • Measurement of electrical, magnetic and electromagnetic fields in industrial and residential areas
  • Measurement of grid parameters and power grid disturbances (voltage changes, frequency, voltage and current harmonics, pulse-shape network feedback).
  • Power network disturbances.

Consulting is also part of our service:

  • Advice to municipal utilities, regional and superregional energy supply companies on EMC problems that occur, for example, at the utility/customer interface
  • Remedy for occurring EMC problems by consultation and, if necessary, measurements with suitable measuring technology on site
  • Consulting, assistance and support for regional and superregional energy supply companies and municipal utilities in implementing the 26th Regulation on the Implementation of the Federal Immission Control Act (26th BImSchV)
  • Joint development of an optimal solution that is individually tailored to the special needs of the customer; cost savings through a systematic and well thought-out approach
  • Specific measurements and calculations of the electrical and magnetic 50 Hz field in accordance with the requirements of the 26th BImSchV – eliminates the need for cost-intensive determination of the emissions of entire plants
  • Supporting in discussions with the competent authorities

Chemistry laboratory

In electrical equipment such as transformers and converters, oils serve as insulating material and coolant. Thermal or electrical faults in this equipment can be diagnosed early by gas-in-oil testing. The aging degree of the insulating oil is also recorded by regular tests. Eurotest tests the insulating oils and then evaluates the results.
