We would like to inform you of our transformer oil testing service based at Acacia Ridge in the south side of Brisbane. Through oil testing, transformers' life can be substantially increased, thus delaying new investment of replacement transformer assets. MLGW’s transformer department performs many diagnostic transformer tests. Transformer oil is not any ordinary oil. Allows extended range measurement for external voltage transformer and current transformer. Each test is an indication of how suitable the insulation liquid is for service. This is because it tends to deteriorate over time. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. 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. Which types of insulating oil can be tested? Online DGA test kit (Image credit: MTE Meter Test Equipment, Switzerland) Online method is adopted for large transformer. 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. Electrical Machine Engineering 1,708 views 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. Furan test is used to determine the life of a transformer and condition of transformer oil in transformer oil. All other oil test results must be recorded in the following network drive: G:\Oildata. Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties. Healthiness of the transformer. Hacı Sabancı Organize Sanayi Bölgesi Anafartalar Cad. The package consists of: • a set of six ASTM fluid quality tests • dissolved gas content of the oil.
