  • Load Tap Changers: Testing Insulating Liquids - SDMyers
    Part 1 of this series addresses how mineral insulating oil ages in the LTC As oil ages in a load tap changer, it polymerizes and forms a resinous, varnish-like film over the contacts and mechanism This segment identifies conditions that cause that filming to proceed more rapidly
  • Elemental analysis of industrial lubricants and oils
    In this article, we discuss the key analytical techniques and testing methods for lubricants, challenges in metal analysis, the role of certified reference materials (CRMs), plus the importance of choosing the right CRM and diluent matrix solvent
  • Determination of Metals in Lubricating Oil by ICP-OES - Agilent
    Regular monitoring of wear metals in oil can diagnose engine wear, so that preventive maintenance procedures can be performed, increasing equipment reliability The analysis of oils for trace metals is routinely carried out as an equipment maintenance program for engines of various types
  • The determination of trace metals in lubricating oils by atomic . . .
    The determination of trace metals in lubricating oils using atomic spectrometric methods is reviewed The importance of such analyses for technical diagnostics as well as the specific sample characteristics related to the analyte form (metallo-organic and metal particles) is discussed
  • A Hyperspectral Analysis-Based Approach for Estimation of Wear Metal . . .
    This study proposes a rapid, non-destructive method for detecting wear metal content in lubricating oil using hyperspectral technology, effectively addressing limitations of conventional oil analysis techniques such as large instrument size, high equipment cost, and complex operations
  • Elemental Analysis Explained and Illustrated - Machinery Lubrication
    Elemental analysis is probably the most fundamental test in the oil analysis toolbox Its history goes back to the 1940s and 1950s when it was used in the railroad industry to determine the presence of wear metals in diesel engine oils
  • Lubricating oil analysis according to ASTM D5185 using the Thermo . . .
    The system is more than capable of meeting the analysis requirements of the standard method ASTM D5185, which details direct analysis of lubricating oils for wear metals and additives
  • Assessing elemental content in lubricants: purposes, techniques, and . . .
    Detection of wear metals: As equipment components wear down during operation, metallic particles are generated and circulated throughout the lubrication system Analysing the elemental content helps in detecting wear metals that are released into the lubricant from machinery components
  • Load Tap Changers: Testing Insulating Liquids
    Load Tap Changers (LTCs) are a common feature on many power transformers, designed to automatically change the transformer’s tap position to the desired level This paper examines the cost-effective and widely recognized maintenance strategy of fluid testing, as outlined by NFPA 70B
