Condition analysis: The basis for optimising maintenance costs and safeguarding reliable operation

Everything from a single source: We have been monitoring insulating oils since 2008 for all stationary transformers and numerous vehicles operated by DB AG.

Accredited test procedures 

  • The proficiency of our test laboratories in Munich for testing in the following areas was accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS): physical, physical-chemical and chemical analyses of lubricants, fuels and insulating oils; element quantification in lubricants via wavelength-dispersive X-ray fluorescence analysis; tribological examinations of lubricants; sampling of lubricants and fuels.
  • The entire list of our accredited test procedures can be found in our accreditation certificate.
  • Routine testing of insulating oils in accordance with DIN EN 60422
  • DB Systemtechnik is QMS certified to the ISO 9001 standard.

Condition analysis of insulating oils used in operation

As experts in the field of lubricant and insulating oil analysis, we provide you with professional services for monitoring and maintaining your electrical resources, vehicles and their components.

Our analyses are a major factor in condition assessment, a tool for early diagnosis and the prevention of damage to your components, and thus make a major contribution to ensuring the lubricative quality of your oil.

Such condition analyses also form the basis for optimising your maintenance costs by facilitating condition-dependent servicing frequencies.
