This thesis investigates a promising and mature technology: Dynamic Thermal Ratings (DTR) of mineral-oil-filled transformers. In short, DTR represents a thermal limit that varies in time as a function of external (ambient) and internal (winding, oil) temperatures of transformers. Considerations of the transformer’s thermal state may allow operating the transformers above their nameplate ratings and thus better utilizing their capacities.The thesis describes a global context, identifies the incentives appearing worldwide, and explains why transformers were chosen as a research object. Next, the reader may find the state of the art on the thermal performance of power transformers, answering the questions:•What are the current and temperature ...
