Station maintenance
We are specialists in the operation and maintenance of hydropower plants.
We also maintain transmission network high voltage substations.
We ensure that the stations are maintained through:
- regular inspections
- visual checks
- functional checks
- checks on the condition of Equipment
- maintenance work.
Furthermore, we carry out the actions and measures required for the proper functioning of the electricity network.
Our engineers and specialists carry out specific maintenance such as protection checks or oil analyses.
Swissgrid has entrusted us with the maintenance of high-voltage substations in the cantons of Valais, Vaud, Fribourg and Berne since 2015.

Additional services
Analysis and adjustment of electrical protection equipment
This service is able to adapt protective equipment to different types of equipment : transformers, electrical lines, alternators, etc.Electrical overhaul - Analysis of insulating oils
The experts in our laboratory officially certified according to ISO/CEI 17025, analyse the insulating oils in the transformers and measuring equipment. They carry out physical and chemical analyses on the oils, examine their dissolved gas content and search for furan components. They then use the results to determine, together with our electrical engineers, the condition of the mechanism and estimate its service life.Electrical simulations
Modelling a power plant's main electrical components makes the simulation of electrical transients possible in order to identify the cause of an incident.References
