The FR3 dielectric fluid universal tester TOR-7 , made by GlobeCore, is used to check the main parameters of insulating fluids used in transformers, switches and other electrical equipment. The device lets you check the quality of the liquid, spot if it’s gone off or been contaminated, and decide what to do with it next. TOR-7 can be used to analyse different types of dielectrics, including mineral, synthetic, silicone, and FR3 bio-oils. During the test, the device measures things like electrical strength, moisture content, dielectric loss tangent, relative permittivity, etc. The device is easy to use, with a control panel and an automatic measurement system. The results will be displayed on the screen and can be saved for future reference. Its compact size and portability make it suitable for use in both laboratory and field settings. TOR-7 is an effective method for the assessment of the technical condition of insulating fluids. This is of paramount importance in ensuring the reliable and safe operation of the equipment. The regular testing of transformers and high-voltage systems has been shown to have a number of benefits. Firstly, it can help to prevent accidents. Secondly, it can reduce the risk of failures. Finally, it can help to extend the lifespan of transformers and high-voltage systems.
