Insulating oil testing


Precise and reliable measurement results

Insulating materials are the potion of electrical equipment. These materials lose their insulating and cooling properties due to impurities and ageing. This damages equipment, causes failures and is consequently often accompanied by high costs.

Testing of insulating materials is therefore legally stipulated and regulated by national and international standards. BAUR oil and insulating material testers are characterised by quality levels recognised worldwide that have direct and indirect effects:

  • Precision, reliability and scope of measurement results
  • Reduction of test expenditure and costs
  • High degree of individualisation and user-friendliness
  • Long device service life

This allows us to make complex technologies against the similarly complex background of standards, easy, safe and profitable for you.

Cable testing and diagnostics


To ensure the flow


The BAUR portfolio covers all the important requirements of mains operators with regard to testing and diagnostics technology in the medium voltage range.

Testing devices are required for successful commissioning of underground cable networks or repairs. Diagnostic testing devices are used for evaluating the cable status, which enables optimised and anticipatory maintenance planning and thus minimises failures. This planning is best established with the BAUR diagnostics system.

With truesinus® digital technology BAUR offers the most modern technology for generating voltage with VLF (Very Low Frequency 0.1 Hz) and thus enables the least destructive testing and diagnostics of modern medium-voltage cables in compliance with the standards.


But even for older cable designs, e.g. paper-insulated mass-impregnated cables, BAUR offers ideal devices for DC voltage testing.

Cable fault location


The shortcut to the source of a fault


In spite of major developments in this field, faults still occur frequently in cable systems for various reasons. In addition to trained personnel, you also need very efficient equipment to rectify faults.

BAUR cable fault location devices and systems cover the entire cable fault location process: During pre-location, the position of the fault is roughly located. The subsequent pinpointing enables precise determination of the cable fault. You can use various measurement methods depending on the kind of fault and cable type.
