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 degradation materials produce CO and CO2 gases. The results of overall power factor tests on power transformers reflect the insulation condition of the windings, barriers, tap changers, bushings and oil. Though bio based transformer oil have gained attention due to stringent environmental issues but their usage is restricted due to limited advantage. 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. Accurate transformer oil test results are an excellent indicator of the condition of your transformers. This is because it tends to deteriorate over time. Oil Tests . Transformer winding resistance measurement 2. The Furan Analysis Process. Testing sequences and procedures are defined by various international standards, many of them set by ASTM. Measure test object of any parameters. This is because it tends to deteriorate over time. Hacı Sabancı Organize Sanayi Bölgesi Anafartalar Cad. Specifications Environment condition. Physical oil condition alerts are taken from IEC 60422, where as oil DGA results are taken from IEC C57.104. Its use to call transformer oil and it a little bit pricey. Through oil testing, transformers' life can be substantially increased, thus delaying new investment of replacement transformer assets. Power down store and browse data (test object set, measurement results, test time) functions. Normally offline method is used. Demand Test Report Routine Test Report (Standard) Type Test Report Special Test Report (Paid) Your Message. 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. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Example Report – Tx Oil Diagnostics. 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. Special tests help to provide useful information to the user. 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. The paper around the leads appears to be burned. Oil sample taking procedure. BA test sets (Breakdown Analyzer test sets) from b2 electronics evaluate condition of transformer insulating fluids (suitable for mineral oils, ester fluids, natural or synthetic, and silicone fluids).This helps you to decide whether the oil has to be changed in order to extend the asset life. Global Transformer Oil Testing Market Report 2020 has complete details about market of Transformer Oil Testing industry, Transformer Oil Testing analysis and current trends.

Same day oil analysis / oil testing from TestOil an oil analysis testing laboratory providing ferrography - filter analysis - tribology - lube oil test services. These standards were selected based on my personal preference however, future revisions may allow the user to select the standard (if requested). In the past, dissolved gas analysis has been the best predictive, noninvasive test for potential failures. Various electrical tests must be performed and their significance and short description are given below. 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. Recently, MLGW has added furan analysis to its diagnostic tests. 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. 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. 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. 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 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. Originally used for their excellent electrical characteristics and not being flammable. 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 … Whenever possible, while commissioning, the voltage should be build up slowly and brought to the full level in about 4 to 6 hours. 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. So what is the offline method. We would like to inform you of our transformer oil testing service based at Acacia Ridge in the south side of Brisbane. Part A: ASTM Transformer Oil Tests. 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. PCB’s: Polychlorinated Biphenyls. The oil used in transformers is hydrocarbon mineral oil. Which types of insulating oil can be tested? No:11 ADANA Email: sales@stdtransformer.com Phone: +90 322 322 22 55 Fax: +90 322 322 22 56 Menu. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. HSB’s screen tests include: Dielectric breakdown, Power factor, Interfacial tension, Acidity, Color, Specific gravity. The oil sample temperature is measured using a built-in thermal sensor and subsequently recorded in the test report. REPORTING Non-volatile memory of the tester stores up to 128 detailed test reports which can be printed out on an integrated printer. 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). There are two major types of transformer oil used in the industry; naphthenic and paraffinic based. First impressions count your transformer oil is within specifications and diagnose internal faults inside the paper, windings, and core. 3. Furan measures the degradation of cellulose paper. The package consists of: • a set of six ASTM fluid quality tests • dissolved gas content of the oil. Electrical Machine Engineering 1,708 views All other oil test results must be recorded in the following network drive: G:\Oildata. Each test is an indication of how suitable the insulation liquid is for service. 2. 4. Samples are generally sent to a laboratory for analysis but portable equipment is available to perform the test in the field. 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. Screen testing evaluates the physical, electrical and chemical attributes of the transformer oil. Transformer vector group test. Store up to 500 groups test results, data transmission online to PC. MLGW’s transformer department performs many diagnostic transformer tests.
