Oil testing in a transformer is performed through various analytical methods to assess the condition and quality of the insulating oil. These tests typically include dissolved gas analysis (DGA), which detects the presence of gases produced by electrical or thermal faults, furan analysis for paper insulation condition, moisture content measurement to ensure the oil’s dielectric strength, and physical property tests such as viscosity and acidity to gauge degradation. By regularly testing the oil temperature in transformer applications, utilities can diagnose potential problems and prevent failures, ensuring efficient and reliable operation.
