A dielectric oil tester, also known as an insulation oil tester or a transformer oil tester, is a specialized device used to evaluate the quality and electrical properties of insulating oils. Insulating oils are commonly used in electrical power equipment, such as transformers and circuit breakers, to provide effective insulation and cooling. The dielectric oil tester works by applying a high voltage across the oil sample and measuring the resulting current flow. This helps to determine the dielectric strength and breakdown voltage of the oil, which indicates its ability to withstand electrical stress without failure. The tester also analyzes other key parameters like resistivity, acidity, and moisture content, which affect the overall performance and longevity of the insulating oil.
ATO provides dielectric strength oil testers with 0 ~ 80KV and 0 ~ 100KV measuring range for your choices, they are all at factory prices. These transformer oil testers apply a high voltage to the oil and measure the breakdown voltage, which indicates the ability of the oil to withstand electrical stress.
