Insulating Fluids Testing

In many electrical systems, insulating fluids are essential. Highly refined mineral oils, silicone fluids, vegetable oil and synthetic esters are all used to guarantee the reliable operation of transformers, medical and safety devices, and even radar technologies. However, such materials can lose their insulating and cooling properties over time, which can lead to damage and failure of equipment and systems – sometimes even catastrophic failures that can cause environmental damage. The testing of insulating fluids is therefore a legal requirement, regulated through national and international standards. But legal compliance is not the only reason to have insulating fluids tested: there are also various economic grounds for doing so – including an extended lifetime for your equipment and improved operational efficiency. 


Information on BAUR oil/fluid testing systems can be found in the sections below.
