Transformer oil is a liquid medium with good insulation performance, which is a mineral oil obtained from natural petroleum through distillation and refining. The selection of transformer oil is generally based on the altitude of the location where the transformer is installed, and transformer oil has good insulation strength. Immersing insulating materials in oil not only improves insulation strength, but also protects them from moisture erosion. The specific heat of transformer oil is also very high and is commonly used as a coolant. Below, Baijian will introduce the knowledge of transformer oil detection to everyone. Transformer oil testing project report: The scope of transformer oil testing report includes plant transformer oil, transformer insulation oil, electrostatic precipitator transformer oil, waste transformer oil, etc. Transformer oil testing report items: furfural testing, breakdown voltage testing, sediment testing, oxidation stability, particle size testing, moisture testing, total hydrocarbon acetylene, flash point testing, water-soluble acid, resistivity, oil sludge testing, dielectric loss factor testing, etc. Transformer oil testing standard: GB/T 7600-2014 Determination of moisture content in transformer oil and turbine oil during operation (Coulomb method) GB/T 7595-2017 Quality of transformer oil during operation GB/T 7602.4-2017 Determination of T501 antioxidant content in transformer oil and turbine oil Part 4: Gas chromatography-mass spectrometry GB/T 14542-2017 Guide for maintenance and management of transformer oil GB/T 7601-2008 Method for determination of moisture content in turbine oil (gas chromatography) GB/T 7602.1-2008 Method for determination of T501 antioxidant content in transformer oil and turbine oil Part 1: Spectrometric method GB/T 7597-2007 Sampling method for power oil (transformer oil and turbine oil) GB/T 7598-2008 Method for determination of water-soluble acids in transformer oil during operation GB/T 7602.2-2008 Transformer oil Method for determination of T501 antioxidant content in turbine oil Part 2: Liquid chromatography GB/T 7602.3-2008 Method for determination of T501 antioxidant content in transformer oil and turbine oil Part 3: Infrared spectroscopy method
