Insulating oil testing is an important test that determines the quality of insulating oil in electrical equipment and transformers. This oil allows electricity to flow smoothly inside the equipment and also helps in controlling heat. Over time, water, sulfur compounds, and other contaminants can enter the insulating oil, which affects the durability and electrical performance of the oil. Therefore, regular testing is very important.
Through this test, the Dielectric strength, Moisture content, Acidity, Breakdown voltage, and Dissolved gas analysis (DGA) of the oil are monitored. DGA specifically identifies the presence of harmful gases inside the transformer and predicts the onset of equipment breakdown or problems. Testing insulating oil at the right time can increase the life of the equipment and prevent unexpected faults or accidents. Therefore, insulating oil testing is an essential and standard maintenance process in the electrical industry and management.
