What is the Purpose of Oil Sampling for Transformers?
Filed under: Uncategorized
Transformers are devices used by the electrical industry to transfer energy from one circuit to another or multiple circuits. They are made up of two or more coils of wire that are used to boost voltage levels to transfer energy over long distances and then lower voltage levels to decrease line losses during transmission. Oil surrounds the coils in a transformer and is crucial for providing cooling, insulation, and protection against corona discharge and arcing. Because of this, it’s vital to take oil samples and perform routine testing to ensure a safe work environment. The experts at North Central Electric share the purpose of transformer oil sampling and how it can help identify issues fast.
The Importance of Taking Routine Oil Samples
Routine oil sampling is a necessary maintenance function that eliminates the possibility of failures, disrupted production, and reduced component life. Oil sample analysis can tell you a lot about the operating conditions of your transformers, including the identification of electrical and thermal stress or chemical contamination. When these instances occur, functionality is reduced, and it can lead to a power outage. By showing the effects of the transformer’s operation on the oil, the analysis confirms the serviceability and condition of the oil in use, which allows better scheduling and maintenance to avoid unexpected outages.
During an oil test, our technicians can determine the dielectric strength, interfacial tension, water concentration, specific gravity, and acidity of your transformer oil. Analysis can also measure the degradation and contamination of the oil to identify if the insulating properties are acceptable. With diagnostic oil testing by our trained and certified technicians, you can make an informed decision regarding your transformer and its insulating fluid to avoid a breakdown or costly problems in the future. If test results are uncertain or your transformer shows signs of deterioration, the service technicians at North Central Electric are prepared and equipped to respond to your needs.
