Cleaning involves:

Assessment: Testing the oil to determine contamination levels.
Filtration: Passing the oil through filters to remove particles.
Water Removal: Using vacuum dehydration or coalescing filters to eliminate moisture.
Adsorption Treatment: Removing dissolved contaminants and oxidation products.
Re-additization (if necessary): Restoring essential additives to the oil.
This process restores the oil’s properties, making it suitable for continued use.

Oil regeneration restores the insulating oil’s properties by removing contaminants like moisture, acids, sludge, and dissolved gases. The process includes filtration to remove particles, vacuum dehydration to eliminate water, and chemical treatment to neutralize acids. Adsorption methods using activated clay or other media can extract dissolved decay products. Regenerated oil regains its dielectric strength and cooling efficiency, extending the transformer’s life and reducing the need for new oil, which is both cost-effective and environmentally friendly.

Intervals should be based on:

Oil Analysis Results: Indicators like high acidity or contamination levels.
Operating Hours: Manufacturer recommendations for service life.
Operating Conditions: Harsh environments may require more frequent changes.
Performance Degradation: Noticeable declines in oil performance.
Regular changes prevent damage from degraded oil and ensure continuous efficient operation.

The transformer turns ratio test is conducted using a specialized transformer turns ratio tester, such as those offered by Globecore. This procedure involves connecting the tester to the primary and secondary terminals of the transformer. The tester applies a known voltage to the primary winding, and then it measures the corresponding voltage on the secondary winding. The ratio of these voltages is calculated, and this result is compared to the expected turns ratio of the transformer. This test helps identify issues like shorted turns or improper winding connections, which can affect transformer performance. Using Globecore equipment ensures accurate and reliable measurements, contributing to effective diagnostics of industrial oils and related systems.

Potassium humate 98 refers to a highly concentrated form of potassium humate, containing 98% humic acid or potassium content. This higher grade offers superior water solubility, making it more effective for immediate nutrient availability and absorption in plants. Compared to lower grades, potassium humate 98 delivers stronger results in terms of nutrient uptake, root stimulation, and crop yield improvement. It is especially suitable for advanced agricultural practices and fertigation systems, where efficiency and performance are critical. Lower grades may contain more impurities or less concentrated humic substances, offering slightly reduced benefits.

A transformer oil containment pit is a designated area designed to safely contain and manage any potential spills or leaks of transformer oil, which is crucial for the proper functioning and insulation of transformers. These pits are typically constructed from materials that can withstand chemical exposure and are equipped with features to prevent oil from entering the environment. They help ensure compliance with environmental regulations and protect against pollution, particularly in facilities where large volumes of transformer oil are used. The design often includes a barrier to hold oil and drainage systems to facilitate spill recovery, ensuring that the integrity of the surrounding environment is maintained. This containment solution is essential for minimizing risks associated with transformer oil management, emphasizing safety, environmental responsibility, and effective response strategies in case of leaks.

A transformer tester is an essential device used to evaluate the insulation resistance and overall health of transformers. It helps in determining if the insulation system within the transformer is functioning properly, which is crucial for the longevity and safety of electrical equipment. Regular testing with a transformer tester can identify potential issues like insulation breakdown, moisture ingress, and other faults early on, allowing for timely maintenance and reducing the risk of transformer failure. Proper diagnostics ensure the transformer operates efficiently, minimizing downtime and costly repairs. To perform these tests safely and effectively, it can be beneficial to also utilize a multimeter for detailed measurements. Use a transformer tester as part of a comprehensive maintenance strategy to ensure reliable operation of your power systems.

The dielectric strength of transformer oil is tested using the Globecore BDV tester, which adheres to the standard transformer oil bdv test procedure. This involves placing a specific volume of oil in a test cell equipped with two electrodes that are positioned at a defined distance apart. As high voltage is gradually applied, the oil is observed for breakdown, which occurs when a conductive path forms between the electrodes. The voltage at which this breakdown occurs is recorded, determining the oil’s dielectric strength. This test is crucial for assessing the insulating properties of transformer oil, ensuring that it can effectively prevent electrical failures in transformers. Proper testing and analysis with a reliable device like Globecore’s BDV tester are essential in maintaining the integrity and performance of transformer oils in industrial applications.
