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. Physical oil condition alerts are taken from IEC 60422, where as oil DGA results are taken from IEC C57.104. Each test is an indication of how suitable the insulation liquid is for service. This is because it tends to deteriorate over time. 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. These standards were selected based on my personal preference however, future revisions may allow the user to select the standard (if requested). Oil Tests . We would like to inform you of our transformer oil testing service based at Acacia Ridge in the south side of Brisbane. 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. 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. Originally used for their excellent electrical characteristics and not being flammable. The results of overall power factor tests on power transformers reflect the insulation condition of the windings, barriers, tap changers, bushings and oil. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Measure test object of any parameters. Part A: ASTM Transformer Oil Tests. Screen testing evaluates the physical, electrical and chemical attributes of the transformer oil. The Furan Analysis Process. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Oil sample taking procedure. 2. There are two major types of transformer oil used in the industry; naphthenic and paraffinic based. 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. Online DGA test kit (Image credit: MTE Meter Test Equipment, Switzerland) Online method is adopted for large transformer. Normally offline method is used. Latest Update: Impact of current COVID-19 situation has been considered in this report while making the analysis. Its use to call transformer oil and it a little bit pricey. Oil Type Transformer Cast Resin Dry Type Transformer. Tractor test reports from the following manufacturers from 1999 to current date are available in .pdf format. Transformer ratio test. The degradation materials produce CO and CO2 gases. In the past, dissolved gas analysis has been the best predictive, noninvasive test for potential failures. Example Report – Tx Oil Diagnostics. 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. All other oil test results must be recorded in the following network drive: G:\Oildata. Recently, MLGW has added furan analysis to its diagnostic tests. Type tests of transformer includes 1. Samples are generally sent to a laboratory for analysis but portable equipment is available to perform the test in the field. PCB’s: Polychlorinated Biphenyls. Same day oil analysis / oil testing from TestOil an oil analysis testing laboratory providing ferrography - filter analysis - tribology - lube oil test services. 4. Special tests help to provide useful information to the user. Power down store and browse data (test object set, measurement results, test time) functions. First impressions count The SDMyers transformer oil testing lab is the largest in the world. 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. By the Furan analysis, we check the condition of paper in transformer oil. Testing sequences and procedures are defined by various international standards, many of them set by ASTM. Furan test is used to determine the life of a transformer and condition of transformer oil in transformer oil. Through oil testing, transformers' life can be substantially increased, thus delaying new investment of replacement transformer assets. 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 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.
