摘要
In view of long-term transformer insulation resistance and dielectric loss measurement, measurement and according to the national standard formula conversion values are not completely consistent, in this paper, a variety of transformers are studied, and the applicable scope of the conversion formula is discussed emphatically, combined with the test results are analyzed of transformer insulation resistance value to temperature and oiliness and dielectric loss tangent to temperature and oiliness, and puts forward suggestions on how to improve the insulation performance of transformer.
