An oxygen concentrator’s zeolite system functions by using pressure swing adsorption (PSA) technology to separate nitrogen from ambient air. Air is drawn into the concentrator, compressed, and then passed through zeolite beds. The porous structure of zeolite selectively adsorbs nitrogen molecules due to their size and polarity, allowing oxygen molecules to pass through. The oxygen-rich air is then delivered to the user, while nitrogen is trapped. Once the zeolite becomes saturated with nitrogen, the pressure is reduced, allowing the nitrogen to be released, and the zeolite is ready for another cycle of adsorption.

The dielectric breakdown voltage of transformer oil is a crucial parameter that indicates its insulating properties and ability to withstand electric stress without failing. Generally, the dielectric breakdown voltage of transformer oil should be at least 30 kV for a solid performance, though higher values are preferred for enhanced safety and reliability in electrical systems. To accurately measure this voltage, you can utilize specialized testers designed by Globecore, which provide precise diagnostics of transformer oil’s insulating qualities. Regular testing is essential to maintain operational efficiency and prevent potential failures in transformers.

An oil-immersed power transformer is a type of transformer that uses insulating oil as a coolant and insulator, allowing it to operate efficiently under high voltage and heavy loads. The oil assists in heat dissipation, which enhances the transformer’s performance and longevity. This type of transformer is commonly used in electrical power distribution systems, including oil immersed distribution transformers, to ensure safe and reliable operation. The insulating oil also plays a crucial role in preventing arcing and flashovers between live components, thereby enhancing the overall safety of the electrical system. Regular maintenance, including cleaning and regeneration of the oil, is essential to prevent oxidation and ensure optimal performance of oil-immersed power transformers.

Eaton oil-filled transformers are predominantly utilized in electrical power distribution systems to step down or step up voltage levels for efficient transmission. They serve critical applications in substations, industrial facilities, and renewable energy installations, ensuring reliable and safe power supply. The oil insulation and cooling properties in these transformers not only enhance performance but also assist in heat dissipation, contributing to their longevity and reliability. These transformers are designed to handle various load conditions, making them ideal for urban areas, rural networks, and anywhere else electrical voltage adjustment is required.

Different transformer oil tests include:
Dielectric strength test: Measures the oil’s ability to withstand electrical stress without breaking down.
Dissolved gas analysis (DGA): Detects gases produced by oil degradation or electrical arcing, indicating potential faults.
Moisture content test: Assesses the amount of water in the oil, as high moisture can reduce insulation effectiveness.
Acidity test: Determines the oil’s acidity level, with higher acidity indicating aging or contamination.
Interfacial tension (IFT) test: Evaluates the oil’s surface tension, which can indicate contamination or oxidation.
Furan analysis: Detects furans in the oil, which are byproducts of paper insulation degradation.
