Analysis of insulating oil: successful accreditation for our laboratory

Our laboratory has just been awarded accreditation by the Swiss Accreditation Service (SAS) in accordance with standard ISO/CEI 17025:2005. Thanks to this certification, the laboratory position itself as a key player for the analysis of insulating oil samples from electrical apparatus used in the generation and distribution of energy.

For a number of years, the HYDRO Exploitation laboratory has offered oil analysis packages that enable appropriate intervention on electrical installations:

  • Targeted analyses during the first months of operation, when the transformer may experience early failure stage problems.
  • Follow-up analyses at regular intervals, during normal service.
  • More frequent and targeted analyses following the appearance of the first symptoms of deterioration, in order to monitor the evolution and potentially estimate the remaining service life of the oil and/or the device.

This information is extremely valuable because it enables us to schedule the replacement of the insulating fluid or the apparatus and avoid unplanned outages.

Thanks to this accreditation, we are today better positioned than ever as a reliable partner for all insulating oil analyses.
