Influence of chemical composition on the gassing behavior of biodegradable dielectric liquids: A review

The increasing adoption of biodegradable dielectric liquids in power transformers introduces new challenges for condition assessment, as Dissolved Gas Analysis (DGA) methods developed for mineral oils often yield inconsistent results when applied to alternative insulating fluids....

Ambient Temperature-Dependent Parameterization of the IEC 60076-7 Top-Oil Thermal Model

Transformer top-oil temperature prediction is essential for reliable thermal assessment and lifetime management. Although the IEC 60076-7 loading guide model is widely adopted for this purpose, its thermal parameters are generally assumed to remain constant regardless of environm...
