It determines the acidity degree of 3 different oil samples at once and saves the results in its internal memory. Thanks to its built-in printer and USB output, test results can be quickly transferred to paper or USB memory.
With its easy calibration feature, titration fluid, extract (separator) etc. At any time, test results can be verified at any time. It guarantees a safe and accurate test result. Thanks to its automatic cleaning feature, the device is self-cleaning.
Why it is necessary:
Air contact may occur in the transformer insulation oil during the opening of any cover or due to leakage in the oil tank and pipelines. As a result, oxidation occurs in the oil, and oxidation can be further accelerated by the effect of catalysts and temperature, such as iron, copper and dissolved metallic compounds in the oil. The acidity formed as a result of oxidation can cause the transformer oil insulation to decrease, the paper used in the coil windings to deteriorate, and also cause the tangent delta value of the oil to increase by creating loss.

GENERAL INFORMATION
What is Transformer Oil?
Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulation properties. It is used in oily transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers. Its functions are to isolate, suppress corona discharge and arcing, and serve as a coolant.
Acidity of Transformer Oil
Urine transformer oil is a harmful property. If the oil becomes acidic, the water content in the oil becomes more oil-soluble. The acidity of the oil degrades the insulating property of the paper insulation of the wrap. Acidity accelerates the oxidation process in the oil. Acid also includes rusting of iron in the presence of moisture.
The acidity test of transformer oil can be used to measure the acidic components of pollutants.
