The TOR-7 silicone transformer oil universal tester made by GlobeCore is designed to test the main characteristics of dielectric liquids, including silicone oils used in transformers, circuit breakers and other electrical equipment. Silicone oils are pretty heat-stable and good at insulating, but their quality can change over time depending on the temperature, moisture, and other things outside. The TOR-7 lets you quickly and accurately measure electrical strength, moisture content, dielectric loss tangent and other important indicators. This data lets you check the oil’s condition regularly, spot early signs of ageing or contamination, and decide whether to keep going or replace the fluid. The device has electronic control, a touch panel and a screen for displaying results. All measurements are taken automatically, so there’s less room for human error and more accuracy. You can save or export the data for further analysis. TOR-7 is great for use in labs and on site in businesses. This device helps to keep equipment running smoothly and makes sure silicone oil in high voltage systems lasts longer.
