Service and maintenance

We carry out service and maintenance work, as well as inspections, tests and measurements related to the operation and electrical safety of electricity distribution systems.

With a service and maintenance agreement, you ensure the monitoring of your electricity distribution system, maintenance and repair measures, and the necessary changes in a controlled manner.

We perform earthing resistance measurements of transformers, as well as integrity measurements of earthing systems. Our measurement protocols and reports are clear and easy to define. As an additional service, we can find out whether the contact voltage (UTP) value requirements are met at the substation (SFS 6001 Appendix M, Mandatory). If the contact voltage value requirement is not met, we make a calculation of the required earthing increase.

In addition, we perform relay tests, battery capacity tests, power quality measurements and condition monitoring of measuring transformers.

Rental services

We rent container and park transformers with various distribution transformers and accessories and services for a short or longer need.

We equip the equipment e.g. construction sites, infrastructure projects, mines and industry.

We also provide backup power generators and distribution boxes for maintenance outages and other needs by installation and maintenance, or by picking them up yourself.
