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
