Lithium zeolite is a crucial component in oxygen concentrators, serving as the adsorbent material that selectively removes nitrogen from ambient air. The zeolite’s crystalline structure contains micropores that preferentially adsorb nitrogen molecules under pressure. By incorporating lithium ions into the zeolite framework, the material’s affinity for nitrogen increases significantly. This enhancement allows for a more efficient separation process, resulting in higher oxygen purity and improved concentrator performance. Lithium zeolite enables oxygen concentrators to deliver medical-grade oxygen by ensuring that the output gas contains a high concentration of oxygen while minimizing the presence of other gases.

The standard procedure for testing a transformer involves several key steps to ensure accurate diagnostics and optimal performance. Firstly, an insulation resistance test is conducted using a megohmmeter to assess the insulation quality between the windings and the ground. Secondly, a transformer turns ratio test is performed to verify the conformity of the turns ratio between the primary and secondary windings, ensuring proper voltage transformation. Next, a power factor test is carried out to evaluate the dielectric losses and insulation condition under operational voltages. Additionally, a temperature rise test may be performed to measure the temperature of the transformer under load conditions, ensuring it operates within safety limits. Lastly, a comprehensive oil analysis should be undertaken using appropriate testers, such as those from Globecore, to check for contaminants, moisture levels, and other factors critical to transformer health. This analysis helps in identifying potential issues like oxidation and degradation of the transformer oil, ensuring the longevity and reliability of the electrical equipment. By following this standard procedure, one can ensure that the transformer functions efficiently and safely, aligning with best practices in the industry.

To check the dielectric strength of transformer oil, a device known as a dielectric strength tester, such as the Globecore D97 tester, is used. This tester applies a voltage to the oil sample until breakdown occurs, providing a measure of its dielectric strength, which is crucial for ensuring the oil’s insulating properties. Water content in transformer oil can be determined using Globecore’s moisture analyzers, which employ various techniques like Karl Fischer titration or capacitive sensing. These tests help ensure that the transformer oil maintains its performance and longevity by verifying that both dielectric strength and moisture levels are within acceptable limits.
