This is because it tends to deteriorate over time. This facility is supported by the Engineering Department of the GE Worldwide Transformer factories and services client’s needs for testing oil, paper insulation from all types of transformers filled with all types of insulating fluids. Oil Tests . Oil pressure test to check the leakages at joints and gaskets on the transformer; Special Tests . Tractor test reports from the following manufacturers from 1999 to current date are available in .pdf format. The package consists of: • a set of six ASTM fluid quality tests • dissolved gas content of the oil. Over the past five decades we have generated millions of test results from thousands of high-voltage units, and we process samples from transformer owners across the country. Oil Type Transformer Cast Resin Dry Type Transformer. The oil used in transformers is hydrocarbon mineral oil. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Power transformer oil test results must be recorded in the MS Access database at G:\Oildata\Transformers Oil Database and a hard copy of test results must be maintained. The DGA test measures dissolved gases in the transformer oil and is capable of detecting: arcing, bad electrical contacts, hot spots, partial discharges, overheating of conductors, oil, tank, and cellulose (paper insulation) degradation. Oil sample taking procedure. Polychlorinated Biphenyls and similarly related compounds were quickly found to be detrimental to the environment and over the years since have been phased out of use. If all the above tests/checks are found satisfactory, a settling time of at least 24 hours, should be allowed for the oil and air released from all points at six hourly intervals, before commissioning the transformer. Rail companies (locomotive HV step-down transformers and switchgear) Oil test laboratories (providing testing services) Transformer and switchgear manufacturers (quality control of oil) Oil companies (testing new oil during manufacture) 5. Store up to 500 groups test results, data transmission online to PC. Which types of insulating oil can be tested? Global Transformer Oil Testing Market Report 2020 Full Report: 2350 USD Multi License (Section): 4700 USD Section Price: As below Page: 115 Chart and Figure: 124 Publisher: BisReport Delivery Time: 24 hour … PCB’s: Polychlorinated Biphenyls. There are two major types of transformer oil used in the industry; naphthenic and paraffinic based. your transformer oil is within specifications and diagnose internal faults inside the paper, windings, and core. Transformer oil is not any ordinary oil. Example Report – Tx Oil Diagnostics. Samples are generally sent to a laboratory for analysis but portable equipment is available to perform the test in the field. Normally offline method is used. In the offline method, during maintenance or after fault, oil sample from transformer is collected and than tested in portable DGA test kit or sent to laboratory. Furan test is used to determine the life of a transformer and condition of transformer oil in transformer oil. The SDMyers transformer oil testing lab is the largest in the world. Transformer oil, a type of insulating and cooling oil used in transformers and other electrical equipment, needs to be tested periodically to ensure that it is still fit for purpose. 4. Recently, MLGW has added furan analysis to its diagnostic tests. Electrical Machine Engineering 1,708 views To order test reports for any other model that was tested at Nebraska Tractor Test Laboratory, or permitted for sale in Nebraska, and for years prior to 1999, please go to publications. So what is the offline method. Insulation Oil Tests . Through oil testing, transformers' life can be substantially increased, thus delaying new investment of replacement transformer assets. Transformer winding resistance measurement 2. Oil Diagnostic Suites for Transformer Oil Diagnostics: The above standard testing is offered in specific diagnostic suites designed to provide the maximum condition information on the transformers. No:11 ADANA Email: sales@stdtransformer.com Phone: +90 322 322 22 55 Fax: +90 322 322 22 56 Menu. Part A: ASTM Transformer Oil Tests. Home » Reports » Global Transformer Oil Testing Market Report, History and Forecast 2019-2026, Breakdown Data by Companies, Key Regions, Types and Application. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. The results of overall power factor tests on power transformers reflect the insulation condition of the windings, barriers, tap changers, bushings and oil. Specifications Environment condition. Though bio based transformer oil have gained attention due to stringent environmental issues but their usage is restricted due to limited advantage. Transformer vector group test. All other oil test results must be recorded in the following network drive: G:\Oildata. This is because it tends to deteriorate over time. Transformer oil, a type of insulating and cooling oil used in transformers and other electrical equipment, needs to be tested periodically to ensure that it is still fit for purpose.
