  1. Welcome all in our Lab.

  2. National Specialized LaboratoryEstablished In 2009Main Aim : Analyzing different types of oil (Mineral,Hydrolic, turbine ) purifying and oil filtration transformer maintenance Employ : 8 people ,5 Analyst and 3 techniciansAmman-AlHurria St. Building No. 100Tel: 00962 6 420 27 32 Fax: 00962 6 420 27 35info@nsl-me.comwww.nsl-me.com

  3. NSL is the first and the only independence Laboratory in Jordan.

  4. - Detect problems inside transformer (electric fault) - Gives informaition about rate of aging (oil and paper( - Varifay Oil Specification Why Analyze transformer oil ?

  5. Provide the appropriate amount of maintenance at the right time. A majority of all transformer failure can be prevented. Oil analysis can be done during operation. majority of all the diagnostic information indicating the condition of the transformer can be derived from oils. Binifaties of Oil Analysis.

  10. Petrolum and oil AnalysisChemical Analysis Friday, November 28, 2014

  11. Water Analysis

  12. Oil Filtration and Purification - Increase dielectric strength - Remove dusts and contaminations - Remove humidity and water content - Degassing the oil. Friday, November 28, 2014

  13. Transformer Signature • When a new transformer is in service, you should start building the transformers analysis history. The recommended tests : • Dissolved Gas Analysis • Water Content • ASTM Package BDV, Visual aspect, Color, Acidity, IFT, Density This basic package is the first step when trying to locate and identify specific transformer problem, the result of these test will allow you to determine what other test are required to be performed in order to have a clear understanding of your transformer actual condition.

  14. Corrosive Sulfur Passivator Content Inhibitor Content Degree of polymerization Oxidation Stability Furan Analysis Special Test NSLoffer special transformer oil tests that allow you to have a more comprehensive view for your transformer oil condition. Friday, November 28, 2014

  15. Dissolved Gas In Oil Universal accepted method to locate incipient Thermal and Electrical fault Friday, November 28, 2014

  16. Fault gases are caused by corona (partial discharge), thermal heating (pyrolysis) and arcing. The Gas Concentrations in the oil depend upon : The volume of oil involved (dilution factors) The age of the transformer (new or old) The type of transformer (Generator or Transmission) (Sealed or free breathing) (Construction of Tap changer) Friday, November 28, 2014

  17. Partial Discharge (Corona)The core of transformer was found to be delaminate due to Corrosion caused by high humidity (73ppm)

  18. Thermal Fault 300-700 oC

  19. Discharge of high energy (Arcing)

  20. Over HeatedCellulosic Degradation –impending insulation failure Friday, November 28, 2014

  21. Increased Stress require more frequent and improved condition monitoring
