Transformer fluid purification is essential because it removes contaminants that adversely affect the oil’s insulating and cooling properties. Contaminants such as moisture, particulate matter, acids, and dissolved gases can lead to:

Insulation Failure: Reduced dielectric strength increases the likelihood of electrical breakdowns.

Overheating: Impurities hinder heat transfer, causing temperature rise and thermal stress.

Accelerated Aging: Contaminants catalyze chemical reactions that degrade both the oil and insulation materials.

Corrosion: Acids and moisture corrode metal components, weakening the transformer’s structural integrity.

By purifying the transformer fluid, these risks are mitigated, ensuring optimal operation, enhancing reliability, and prolonging the service life of the transformer.

Transformer Moisture Removal plays a pivotal role in maintaining the optimal performance of electrical transformers. Moisture present in transformer oil diminishes its insulating capabilities, which can lead to electrical failures such as short circuits and partial discharges. These failures not only disrupt the normal operation of the transformer but also pose safety hazards. Furthermore, moisture accelerates the chemical degradation of the oil, resulting in the formation of sludge and acids that corrode internal components like windings and core laminations. By removing moisture, the insulating properties of the oil are preserved, ensuring efficient electrical insulation and effective cooling. This leads to enhanced reliability, reduced energy losses, and prolonged service life of the transformer, ultimately contributing to consistent and safe power distribution.

The winding resistance test of a transformer is conducted using a precision ohmmeter or a transformer testing system specifically designed for this purpose. The procedure involves disconnecting the transformer from the power supply and ensuring its safety. Connect the ohmmeter leads to the winding terminals, making sure to select the correct winding to test. The transformer testing system applies a low measurement current and records the resistance value. This test helps identify issues like poor connections or damaged windings, ensuring the transformer operates efficiently and reduces the risk of failure. Regular testing is crucial for maintenance and compliance with industry standards.

The manufacturing process of potassium humate generally involves:
Raw Material Selection: High-quality leonardite or lignite is chosen as the raw material because of its rich humic substance content.
Alkaline Extraction: The raw material is treated with potassium hydroxide (KOH) to dissolve humic and fulvic acids from the source.
Filtration: The resulting solution is filtered to remove solid residues, yielding a pure humic acid solution.
Neutralization and Concentration: The solution may be neutralized and concentrated to enhance the potassium content.
Drying or Granulating: Depending on the final product, the liquid can either be dried to produce powder or granules, or it can be left in liquid form for packaging.
Packaging: The final potassium humate product is packaged for distribution in various forms such as liquid, powder, granules, or flakes
