The insulation performance of SF_(6)insulated high voltage direct current apparatus are often analysed in a pure electric field or electro-thermal coupled field while the fluid behaviour of SF_(6)gas flow is often ign...
Insulation breakdown of dry-type valve-side bushing cores under electrothermal compound stress has become a key factor limiting the safe and stable operation of the converter transformer.Based on slices of the real bu...
The dielectric loss and capacitance test of the transformer can effectively find out whether the transformer is damp, and the insulation is aging, and the oil quality is deteriorating. The insulation is stuck with oil...
