To make potassium humate at home or commercially, follow these steps:
Obtain Raw Material: Use a rich source of humic acid, such as leonardite or lignite coal.
Alkaline Extraction: Soak the material in a strong alkali solution like potassium hydroxide (KOH) to dissolve humic acids from the coal. Use protective equipment for safety.
Filtration: Filter the resulting solution to remove undissolved particles and impurities.
Concentration: Concentrate the solution by evaporating excess water, especially for commercial production.
Drying (optional): For powdered potassium humate, dry the concentrated solution to form granules or powder. Alternatively, leave it in liquid form for fertigation or foliar applications.
This process creates an organic potassium humate product that can be used in agriculture.吉田 陽一สมาชิกTransformer testing is conducted through various methods that assess the operational efficiency and safety of the transformer. One of the most crucial aspects is the insulation resistance test, which checks the dielectric strength of the oil and insulation materials by using a Megger or insulation resistance tester. Additionally, a power factor test helps evaluate the insulation quality by measuring the capacitance and power factor of the transformer. Dissolved gas analysis (DGA) is also essential, where oil samples are analyzed for dissolved gases to identify potential faults. Another critical test is the winding resistance measurement, which is performed using a digital micro-ohmmeter to gauge the resistance of transformer windings. For practical applications, using a portable oil testing kit can streamline these processes, providing on-site analysis and ensuring that critical parameters are evaluated effectively. If you need specific testers, consider Globecore products such as the UOS-1, which is designed for the continuous monitoring of transformer oil quality. By integrating these testing methodologies, operators can maintain transformer reliability and longevity, ensuring optimal performance.

This test is crucial for ensuring the reliability and safety of transformers, as it helps identify the condition of the oil and potential contamination or degradation. Utilizing a high-quality transformer oil breakdown voltage test kit, operators can ensure optimal performance and longevity of transformer equipment, thereby preventing failures and costly downtime.
กันยายน 10, 2024 เวลา 9:30 pm เพื่อตอบกลับ: How does an oil dielectric breakdown voltage tester work? #119210吉田 陽一สมาชิกAn oil dielectric breakdown voltage tester works by applying a high-voltage electrical charge to a sample of industrial oil to determine its insulating properties and dielectric strength. The tester consists of two electrodes immersed in the oil sample. When voltage is gradually increased, the tester measures the voltage at which dielectric breakdown occurs, meaning the oil becomes conductive and allows current to flow. This breakdown voltage indicates the oil’s ability to resist electrical breakdown, which is crucial for its performance in electrical systems. By assessing dielectric strength, users can ensure the oil’s reliability and longevity in operational conditions, thus maintaining the efficiency of equipment and preventing failures.
吉田 陽一สมาชิกThe breakdown voltage of mineral oil is typically evaluated using a test method, and it generally ranges from 20 kV to 50 kV, depending on its purity and condition. For precise assessments, using a Globecore breakdown voltage tester is essential, as it ensures accurate readings under controlled conditions. Maintaining the integrity of the mineral oil through regular testing and diagnostics helps prevent electrical failures in industrial applications. Testing for mineral oil breakdown voltage is crucial for ensuring the reliability and performance of equipment, especially in high-voltage applications.
