Specifications Environment condition. Oil Tests . Modern oil-filled power transformers should have power factors of 0.5% or less, corrected to 20°C (68°F), for individual windings to ground (CH and CL) and interwinding insulations (CHL). The degradation materials produce CO and CO2 gases. 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. The SDMyers transformer oil testing lab is the largest in the world. Store up to 500 groups test results, data transmission online to PC. PCB’s: Polychlorinated Biphenyls. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties.

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. 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. By the Furan analysis, we check the condition of paper in transformer oil. Home » Reports » Global Transformer Oil Testing Market Report, History and Forecast 2019-2026, Breakdown Data by Companies, Key Regions, Types and Application. Originally used for their excellent electrical characteristics and not being flammable. Samples are generally sent to a laboratory for analysis but portable equipment is available to perform the test in the field. Its use to call transformer oil and it a little bit pricey. Transformer vector group test. Power down store and browse data (test object set, measurement results, test time) functions. 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. Transformer oil is not any ordinary oil. Physical oil condition alerts are taken from IEC 60422, where as oil DGA results are taken from IEC C57.104. 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. So what is the offline method. The results of overall power factor tests on power transformers reflect the insulation condition of the windings, barriers, tap changers, bushings and oil. Special tests help to provide useful information to the user. Type tests of transformer includes 1. It is used in oil-filled transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers.Its functions are to insulate, suppress corona discharge and arcing, and to serve as a coolant. Part A: ASTM Transformer Oil Tests. 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. Testing sequences and procedures are defined by various international standards, many of them set by ASTM. The oil that provides insulation and cooling properties for a transformer should be tested before the transformer is energized, and periodically as a part of a regular maintenance schedule. 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. 4. We would like to inform you of our transformer oil testing service based at Acacia Ridge in the south side of Brisbane. MLGW’s transformer department performs many diagnostic transformer tests. Accurate transformer oil test results are an excellent indicator of the condition of your transformers. Once oil filling is completed, various pre‐commissioning checks and tests are performed to ensure the healthiness of the transformer (or reactor) prior to its energization. The Furan Analysis Process. 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. Example Report – Tx Oil Diagnostics. 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. Screen testing evaluates the physical, electrical and chemical attributes of the transformer oil. The oil used in transformers is hydrocarbon mineral oil. The paper around the leads appears to be burned. 3. Each test is an indication of how suitable the insulation liquid is for service. Healthiness of the transformer. 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. 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. Transformer oil testing is one of the important parts of a power transformer.This test will be performed when your power transformer cooling system is an oil type. 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.

REPORTING Non-volatile memory of the tester stores up to 128 detailed test reports which can be printed out on an integrated printer. There are two major types of transformer oil used in the industry; naphthenic and paraffinic based. Through oil testing, transformers' life can be substantially increased, thus delaying new investment of replacement transformer assets. 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. In the past, dissolved gas analysis has been the best predictive, noninvasive test for potential failures. That means we have the capability and capacity to provide effective, accurate test results quickly. This is because it tends to deteriorate over time. Global Transformer Oil Testing Market Report 2020 has complete details about market of Transformer Oil Testing industry, Transformer Oil Testing analysis and current trends. These standards were selected based on my personal preference however, future revisions may allow the user to select the standard (if requested). Transformer ratio test. The oil sample temperature is measured using a built-in thermal sensor and subsequently recorded in the test report. Recently, MLGW has added furan analysis to its diagnostic tests. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Global Transformer Oil Testing Market Growth (Status and Outlook) 2019-2024 has complete details about market of Transformer Oil Testing industry, Transformer Oil Testing analysis and current trends. Furan measures the degradation of cellulose paper. This is because it tends to deteriorate over time. Measure test object of any parameters. These tests are done to assess the condition of transformer after installation and compare the test results of all the low voltage tests with the factory test reports. 2. Allows extended range measurement for external voltage transformer and current transformer. Whenever possible, while commissioning, the voltage should be build up slowly and brought to the full level in about 4 to 6 hours. Oil Type Transformer Cast Resin Dry Type Transformer.
