OVERVIEW
The fully automatic oil acidity tester is a high-precision, fully digital industrial testing equipment independently developed by national standards and specifications. Transformer and turbine oil acid value testing is a routine testing item for oil-filled electrical equipment in power systems and industrial and mining enterprises. This instrument determines the acid value of the above oil products. It adopts a fully digital microcomputer control system based on the chemical analysis’s acid-base neutralization reaction principle. It uses a detection method combining acid extraction and neutralisation titration to ensure that the measurement precision and accuracy reach the advanced level of the industry.

FAQ
Q: How do you test the acidity of oil?
A: To test the oil’s acidity, the sample is weighed, mixed with a solution, and titrated with potassium hydroxide (KOH) until the acidity is neutralized. This process, known as the neutralisation number, determines the oil’s acidity content in mgKOH/g.
Q: What is a transformer oil acidity test?
A: The transformer oil acidity test measures the acids formed due to transformer oil oxidation when exposed to high temperatures and oxygen, with small metal particles acting as catalysts. An increase in the oil’s acid value reduces its insulating properties.
Q: How do we remove acidity from transformer oil?
A: To remove acidity from transformer oil, two methods are commonly used:
- Filtration and Adsorption: This involves using filter or adsorbent materials, such as activated charcoal, to remove acidic impurities and lower the oil’s acid value.
- Thermal Treatment: The oil is heated to a high temperature to break down acidic compounds, reducing their value.
