What kind of transformer oil test should be done?

Application:
Insulating oil is commonly used in electric power equipment, and the Dielectric Strength is a broad metric for insulating oil. ASSEN AS-023 series bdv oil tester is designed specifically to measure the dielectric strength of insulating oils. AS-023A Automatic Transformer Oil Tester is created following the IEC156 international standard, which adopts an industrial single chip as the controller, uses a big integrated circuit, a new type of I/O interface, and an LCD displayer, all combined with unique testing and anti-jamming technologies to significantly increase tester performance.

Product Features
1) 7-inch color LCD touch screen control
2）The testing process meets the requirements of IEC156/IS6792/BS5874, ASTMD1816, ASTMD877, ASTMD1816 standard
3) Test standards can be selected according to needs
4）Provide PC application software to upload test data to produce a WORD test report

How often should you test transformer oil?
According to the transformer operating regulations, transformer oil must be tested every year. Depending on the voltage level, the test cycle and items are also different. The test cycle for 66~550kV transformers is 1 year, and the test cycle for transformers of 35kV and below is 3 years. The test items generally include the oil dielectric strength test, oil dielectric loss factor tanδ test, simplified test, etc. For transformers of 330kV and above, other test items should be added.
