A transformer turns ratio tester is an essential device used for evaluating the turns ratio of transformers, which is crucial for assessing their operational integrity. It measures the ratio of the primary winding voltage to the secondary winding voltage and can identify issues like improper connections or faults within the transformer. Using this tester helps in preventive maintenance, ensuring transformers operate efficiently and safely. Regular testing with a transformer turns ratio tester can help in diagnosing potential problems before they lead to transformer failures, thus enhancing reliability in industrial applications. This equipment is vital in the broader context of diagnostic tools like the transformer megger test, ensuring the longevity and optimal performance of transformers and associated electrical equipment.

Crush the Coal: Start by crushing the lignite coal into a fine powder to increase surface area for extraction.
Alkaline Extraction: Add potassium hydroxide (KOH) to the powdered lignite coal in a large container. The alkali dissolves the humic and fulvic acids present in the coal, producing a potassium-rich solution.
Stirring and Heating: Heat and stir the mixture to speed up the reaction and extract more humic acid from the coal.
Filtration: After sufficient extraction, filter the mixture to separate the humic acid solution from the solid residue.
Neutralization: Neutralize the solution to stabilize the potassium humate, making it safe for agricultural use.
Drying (Optional): The potassium humate solution can be concentrated and dried to produce powder or granules.
This process allows for the efficient production of potassium humate from lignite coal.後藤 零MemberThe BDV test of transformer oil, also known as breakdown voltage testing, is a crucial diagnostic procedure used to assess the electrical insulating properties of transformer oil. This test measures the voltage at which the oil breaks down and conducts electricity, indicating its ability to insulate electrical components in transformers. A high BDV value suggests good insulation quality, while a low value may indicate contamination or deterioration of the oil. Globecore offers advanced testers specifically designed for conducting BDV tests, which provide accurate and reliable measurements to ensure the safe and efficient operation of transformers. Regular BDV testing is essential for maintaining transformer reliability and preventing electrical failures.
September 7, 2024 at 8:07 am in reply to: What is the dielectric strength test of transformer oil? #118903後藤 零MemberThe dielectric strength test of transformer oil measures the oil’s ability to withstand electrical stress without breaking down. This test is crucial in assessing the quality and suitability of transformer oil for electrical insulation purposes. The test involves applying a gradually increasing voltage to a sample of the oil until it fails and conducts electricity, indicating the breakdown point. A higher dielectric strength denotes better insulating properties, which is essential for the safe operation of electrical transformers. Globecore offers advanced testers specifically designed for evaluating the dielectric strength of transformer oil, providing accurate and reliable results. When considering a dielectric strength testing solution, it’s essential to check the transformer oil bdv test kit price in India to ensure you choose the right equipment that matches your budget and operational needs.
後藤 零MemberA BDV testing kit typically includes a high-voltage tester designed to measure the breakdown voltage of industrial oils. It generally consists of components such as an oil sample container, electrodes for conducting the test, a power supply unit to generate high voltage, and a readout device or digital display to show the breakdown voltage results. Additionally, safety equipment such as protective gloves and eyewear may be included to ensure safe handling during the testing process. Accurate BDV testing is crucial for determining the insulating properties of oils, making a reliable kit essential for effective assessment.
